Upgrade your tractor’s lighting with North American-made quality and unmatched performance. Our BTS Lighting 8-Pod LED Kit utilizes genuine Diode Dynamics SS3 Flush Mount pods in your choice of Sport or Pro power levels – both in the Flood beam pattern for wide, even illumination. This kit is engineered for plug-and-play installation on popular agricultural equipment (John Deere, Case IH, New Holland, and more) using either H11/880 or 2-pin Deutsch connectors. With powder-coated Canadian stainless steel brackets adapting the pods to factory light openings, you get a seamless OEM-like fit with no cutting or splicing required. The result is a true North American product: American-engineered LED lighting paired with Canadian-built hardware – a combination that delivers superior brightness, durability, and easy installation to keep you productive after dark.

Key Features & Benefits

• Unmatched 3″ Pod Performance: Diode Dynamics SS3 pods deliver “higher output intensity than any other 3-inch light on the market,” thanks to custom-engineered TIR optics. Each pod focuses LED light only where you need it, minimizing glare and wasted output. The Flood pattern provides a uniform 60° spread for even, widespread illumination – perfect for low-speed field work and yard operations. Say goodbye to dim factory lights: SS3 Sport pods emit ~1,300 lumens each, while SS3 Pro pods produce ~2,700 lumens each, vastly outperforming typical halogen work lamps.

• Sport vs. Pro – Choose Your Brightness: Both Sport and Pro models use high-intensity LEDs and advanced optics, but the Pro level outputs roughly double the total power of Sport. Sport pods draw just 14.5 watts each, ideal for efficient, cooler operation while still giving a major illumination boost. Pro pods draw 36 watts each to maximize brightness – perfect for those needing the absolute highest light output. No matter which you choose, you’re getting top-tier performance engineered and assembled in the USA for quality you can trust.

• Premium Build – Built to Last: Diode Dynamics SS3 pods feature durable powder-coated aluminum housings with integrated pin-fin heat sinks for efficient passive cooling. The lenses are molded polycarbonate, and the units are fully sealed to IP69K standards – meaning they’re waterproof even against high-pressure spray. Each pod is extensively tested for vibration, moisture, and extreme temperatures from -40°F to 185°F to ensure reliable operation in harsh farm environments. We stand behind this quality with an industry-leading 8-year limited warranty on the lights (and limited lifetime support from Diode Dynamics on select products). Rest assured, this kit is an investment in long-term, trouble-free lighting.

• Amber Backlight Accent (Optional): Every SS3 pod in this kit comes with an amber backlight feature – a low-power LED backlight that illuminates the optic with a distinctive amber glow. This can function as an accent or marker light for added visibility. The included wiring adapters are 4-pin, providing a third wire for the backlight circuit. You can easily tap the backlight into your marker light or ignition circuit for synchronized running lights (additional wiring for the backlight is optional and not required for main operation). When powered, the amber backlight gives a modern look “fully illuminating the TIR optic” for a signature appearance. It’s a unique feature that most generic tractor lights don’t offer, helping your machine stand out and stay safe.

• Complete 8-Light Kit – Plug & Play: This kit includes eight (8) SS3 flush-mount pods in Flood beam (Sport or Pro trim) along with eight custom BTS mounting brackets and all necessary hardware. Our brackets are laser-cut from stainless steel (Canadian-sourced) and powder coated for maximum corrosion resistance – they secure the pods into your tractor’s existing light recesses for a clean, factory look. We also provide the correct plug-and-play adapters: 1× H8/H9/H11-to-Deutsch 4-pin or 1 × Deutsch 2-pin to Deutsch 4-pin harness adapters. No cutting or splicing of your OEM wiring is needed – simply unplug your old lights and plug in the SS3 pods using the appropriate adapter. The inclusion of both H11 (880 series) and 2-pin Deutsch connectors means this kit will plug directly into most late-model tractors and combines that use those standard connectors. Installation can be done in ~1 hour with basic tools – truly an easy DIY upgrade for even busy farmers.

• True North American Quality: Unlike many off-brand import lights, this kit is a collaboration of American and Canadian engineering. Diode Dynamics designs, engineers, and manufactures the Stage Series pods in the USA, ensuring top-notch quality control and cutting-edge LED technology. BTS Lighting’s brackets are proudly fabricated in Canada from high-grade steel. The result is a rugged setup built for the demands of North American agriculture. Don’t settle for dim OEM bulbs or inferior aftermarket lights – this kit offers a purpose-built solution with better output, durability, and fit. It’s also exclusively sold by BTS Lighting, so you know you’re getting a product tailored to your needs, backed by our expertise and Diode’s warranty support.

Compatibility & Fitment

This pod LED upgrade kit is designed for a wide range of agricultural machinery, including tractors, combines, sprayers, and construction equipment that use flush or recessed work lights. It is compatible with many models from John Deere, Case IH, New Holland, AGCO, and others, especially those using H11 (880 series) or Deutsch 2-pin connectors for factory work lights. For example, it’s a plug-in replacement for many John Deere 7xxx, 8xxx, 9xxx series tractors (e.g. 7020, 7030, 8020, 8030, 8R, 9R series) which commonly use H11/880 connectors in their cab and fender lights. It also fits numerous Case IH Steiger and Magnum tractors and New Holland T7/T8 series that use 2-pin Deutsch connectors for work lamps.

Each SS3 pod is a compact 3” size, making it easy to flush-mount in place of OEM lights with similar dimensions. The included brackets and gaskets take up any slack, ensuring a snug, weather-tight fit. If your machine originally uses standard small rectangular or oval work lights (common 4” size class or smaller), there’s a good chance this kit will fit with little to no modification. The H11 to DT and 2-pin DT adapters cover the most prevalent connector types – “the same connector commonly used on most tractors and combines” for plug-and-play installation.

Note: While this kit is broadly compatible, please verify your equipment’s light openings and connector type. Our brackets align with OEM mounting points for many popular models, but slight alterations (like drilling new mounting holes) may be needed on some applications. If you have any questions about fitment, contact BTS Lighting for guidance – we’re here to ensure a perfect fit on your specific machine.

Sport vs. Pro – Which Should You Choose?

Both Sport and Pro versions of the SS3 Flood Pod will vastly improve your visibility, but there are some differences to consider:

• Brightness: The SS3 Sport (Flood) emits about 1,300 lumens (measured) per pod. This is already several times brighter than typical halogen tractor lights. The SS3 Pro (Flood) steps up to roughly 2,700 lumens per pod – over double the brightness of the Sport, using higher-powered LEDs. If you frequently work in pitch-black fields or need the greatest reach, the Pro is the ultimate choice. For general farmyard tasks or if you’re on a tighter budget, the Sport will still exceed expectations with efficient output.

• Power Draw: Each Sport pod consumes ~14.5W, whereas each Pro pod draws ~36W. Both are designed for 9-30V systems, so they’ll work on 12V or 24V tractors alike. The Sport’s lower wattage means minimal strain on your electrical system – you could run all eight Sport pods and still often draw less power than the original halogens. The Pro’s higher draw is still reasonable for most equipment, but if you have dozens of other accessories or weaker alternators, ensure your power system can support ~288W (36×8) plus any other loads. In most modern tractors this is no problem.

• Application: Sport models are an excellent bang-for-the-buck, providing ample brightness for typical farming, acreage, or construction use. Pro models are ideal for those who demand the brightest fields of view – e.g. large-scale operations, custom applicators running through the night, or users who want to future-proof their lighting. Both feature the same build quality, beam pattern, and amber backlight; you’re mainly deciding on brightness and price point.

No matter which you choose, you’re getting the same proven Diode Dynamics quality and optics. Many customers choose Sport for rear or side lights and Pro for front-facing lights – you can mix and match to suit your needs. If you need help deciding, reach out to us for personalized advice.

Easy Installation in Under 1 Hour

One of the biggest advantages of this kit is the truly plug-and-play installation. We’ve done the engineering work so you don’t have to fabricate brackets or splice wires. Here’s what to expect during install:

• Mounting the Pods: The SS3 flush pods come with a flush-mount bezel and gasket. Using our custom brackets, these pods will bolt into the existing mounting holes/locations of your OEM lights (whether they’re on the cab roof, fenders, grille, or elsewhere). The flush bezel provides a clean, low-profile look “with a clean, factory-style appearance” once installed. Simply remove your old light fixtures, position the SS3 pods with the bracket and gasket, and secure them using the provided stainless hardware. No cutting of new holes is required – the brackets are designed to adapt the SS3 to the factory opening. All required bolts, nuts, and templates are included.

• Wiring & Adapters: Each Diode Dynamics pod has a Deutsch DT output on the back with a short pigtail. We include adapter harnesses that connect this directly to your machine’s wiring. If your tractor uses an H11 (also known as 880/881) connector for the factory light, use the H11-to-DT adapter on that light’s plug – it will snap right in, linking the two power wires to the pod’s 4-pin input (and providing the extra backlight lead). If your equipment uses a 2-pin Deutsch connector already (common on many late-model Case IH/New Holland), use the DT2-to-DT4 adapter. In some cases, older machines may have other connectors (like Weather-Pack or Packard): we can supply additional adapter types if needed – just ask. No wire cutting, crimping or soldering is needed; the adapters make it truly plug-and-play.

• Backlight Wiring (Optional): The main 2-pin connections power the primary LEDs (the white flood). The included adapters also have a third wire for the amber backlight circuit. This third wire is left loose so you can choose how to use it. For example, many will tap it into the running light or marker light circuit so that the amber backlight comes on with your running lights. Alternatively, you could wire them to a toggle switch for an “amber glow” mode at your discretion. Using the backlight is optional and additional hookup time may be needed. If you decide not to use it, simply cap or tie off the extra lead – the main lights will still work independently. (The pods come with instructions on backlight wiring, and “to power the backlight, use the included harness to tap your desired vehicle function”.)

• Test & Aim: Once everything is mounted and plugged in, test each light. The SS3 floods throw a broad spread, so aim them slightly downward for the best foreground illumination without glare. Since these are flood beams (not on-road driving lights), precise aiming is not critical, but for consistency align the pods evenly. Tighten all hardware and you’re done. Total install time is roughly 1 hour with basic hand tools – quicker if you have an extra hand to help.

If any questions arise, BTS Lighting’s support is here to help via phone or email. We’ve designed this kit to be as straightforward as possible, so you can spend more time working and less time wrenching.

Frequently Asked Questions (FAQ)

Q: What tractor models will this kit fit?
A: This kit is designed to fit a broad range of tractors and farm equipment. It’s essentially universal for machines that use standard 3-4 inch work lights and either H11 (880 series) or Deutsch 2-pin connectors. We specifically target John Deere 6, 7, 8, 9 Series tractors, including R series and earlier 7020/7030/8020/8030 series, which commonly use the H11 style connectors for cab and fender lights. It’s also compatible with many Case IH tractors (Magnum, Steiger), New Holland tractors (T7, T8), AGCO brands (Challenger, Fendt, etc.), and even construction equipment or sprayers that have similar-size lights. The included adapter harnesses cover the most popular connectors – if your machine uses a different connector, let us know and we can advise on a solution. In short, if your OEM lights are small round or rectangular halogens, there’s a great chance this high-output LED kit will fit right in and “plug and play on most tractors and combines”.

Q: Is any cutting or drilling required to install the flush mount pods?
A: No cutting of your machine is required. The SS3 is a flush-mount style pod, but we’ve engineered custom brackets to mount them in factory locations without needing to cut new holes. The term “flush mount” might make you think you have to cut the body or bumper – not in this case. If your original lights are surface-mounted, our bracket adapts the SS3 into that space cleanly. We provide drilling templates only as a backup in case you want to custom-locate the pods, but for factory replacement use, your existing openings are utilized. All mounting points on the brackets align with OEM bolt holes or easily accessible areas. The result looks factory-installed. Likewise, no wire splicing is needed – the adapters take care of the wiring connections. The whole install is designed to be reversible as well, so you can return to stock if needed (but we doubt you’ll want to after seeing the light output!).

Q: What’s the difference between the Sport and Pro versions?
A: The main difference is brightness (and power). SS3 Sport pods use slightly smaller LED chips and draw ~14.5 watts to produce ~1,300 lumens each. SS3 Pro pods use larger, high-output LED emitters, drawing ~36 watts to produce ~2,700 lumens each – about double the light of the Sport. Physically, they look the same and both have the amber backlight feature. Both are far brighter than stock tractor lights. Choose Sport if you want a very solid upgrade that’s more budget-friendly or easier on the electrical system. Choose Pro if you want the absolute maximum illumination available in this size, or if you’re upgrading a large machine where you need light spread over a bigger area. Either way, you’re getting top-tier quality; it’s purely about how much light you need. (Some users even mix them, e.g. using Pros for front-facing lights and Sports for rear/side lights.)

Q: How does the amber backlight work? Do I have to use it?
A: The amber backlight is a built-in secondary LED in each pod that creates a low-intensity amber glow. It’s a great feature for adding visibility or a custom look, for example using it as a daytime running light or courtesy light. However, it’s completely optional to hook up. Each pod has a 4-pin Deutsch connector: two pins power the main white beam, and the other two pins power the amber backlight. The included harness adapters bring out that third wire – you can connect it to any 12V source you want the backlight tied to (such as your running lights, ignition, or a separate switch). If you choose not to use the backlighting, simply leave that wire capped; the main lights will still function normally on the 2-pin circuit. If you do wire it in, you’ll get a beautiful amber backlit glow when activated (which looks similar to modern automotive LED accents). It’s a nice bonus feature Diode Dynamics includes “fully illuminating the TIR optic” in amber, but again, it’s up to you if and how you use it.

Q: Are these lights road legal or DOT approved?
A: The Flood pattern used in this kit is designed for off-road and work light use. It provides a wide 60×60 degree illumination and is not intended for on-road driving (no cutoff for oncoming traffic). That said, these are often used on tractors, combines, and utility vehicles primarily off public roads or only occasionally on-road. If you do drive on public roads, you may want to wire them to turn off when driving, or aim them downward to avoid glare. Diode Dynamics does offer SAE-compliant Driving and Fog patterns in the SS3 line, but for maximum field illumination the Flood is the optimal choice. There is no DOT regulation for auxiliary work lights on agricultural vehicles, so using these on your tractor is perfectly fine. For road travel, just use common sense – dim or turn off the floods to avoid blinding others. The amber backlight, however, is low intensity and could be used as a marker light on-road if desired (amber is a legal color for front/rear markers in most areas). Always check local lighting regulations if uncertain.

Q: How do these compare to OEM or other aftermarket lights (like Larsen Lights)?
A: In short, this kit outperforms most OEM halogen and generic LED solutions by a large margin. Many stock tractor work lights are 35W or 55W halogen bulbs that might produce 400-800 lumens each in actual use. Replacing eight of those with eight SS3 pods (Sport ~1,300 lm each, Pro ~2,700 lm each) means you’re easily getting 2-5x the total brightness, while often using less power overall. The controlled TIR optics also put the light right where you need it, instead of scattering it. Compared to typical aftermarket “fit form” LED replacements (like common 24W or 65W LED floods), the SS3 pods still have an edge. For example, many drop-in LED oval lights advertise ~2,000 lumens; the SS3 Pro is 2,700 lm with better focus. Diode Dynamics’ quality and testing also ensure longevity – these pods run cool and are rigorously validated, whereas cheaper lights may overheat or fail in tough conditions. Additionally, our kit’s amber backlight and complete harness/bracket solution add value that most competitors (like Larsen or Tiger lights kits) don’t include. You’re getting an American-made, warrantied product built for performance. In terms of warranty, Diode Dynamics offers up to an 8-year limited warranty on these, versus many aftermarket lights with 1-2 year warranties. So, while the upfront cost is higher than some basic LED bulbs, the long-term brightness and reliability make this a superior investment. Our goal is to deliver the best tractor lighting kit on the market – one that truly makes your night work easier and safer.

Q: Can I purchase individual pods or smaller kits?
A: Yes. We offer the SS3 Flush Mount pods individually as well – useful if you need a single replacement or want to add an extra light (for example, some larger tractors or sprayers have an odd number of lights including side-facing lamps). You can choose Sport or Pro as needed, and we’ll provide the correct adapter harness (H11 or 2-pin) for each. We also plan to offer smaller bundle options (e.g. 2-pod or 4-pod sets) if you don’t require all 8 at once. However, buying the full 8-pod kit will give you the best value per pod and ensures you have everything to do a complete swap on compatible machines (most larger tractors use 8 work lights, typically 4 front + 4 rear). If you’re unsure how many you need or which configuration, feel free to contact us – we can guide you to the right product for your needs.
