Product Overview
Enthusiasts often settle for 12‑volt polycarbonate watermelon lights with simple diode arrays that are dim, prone to moisture and limited to one output mode. For example, a typical dual‑color “Dual Fury” light uses just 2 amber and 2 white LEDs behind a clear polycarbonate lens and only operates on 12 V. Even the previous Alpha Series dual‑color light produced 5500 lumens and used a three‑wire H11 bulb but remained weather‑resistant rather than fully waterproof. The Gen 2 Glass is Class Amber/White light solves these problems by combining a tempered‑glass star lens with our advanced AlphaFit G2 LED bulb. It offers dual‑function capability, a broader voltage range (12 V and 24 V), increased output and a sealed IP68 housing for condensation‑free performance—making it the ultimate upgrade for show trucks, daily haulers and custom builds.
Key Features & Benefits
Amber Lens with White LED Chip – Balanced Brightness & Style
Most dual‑color watermelon lights rely on clear lenses to switch colors. Our Gen 2 light retains an amber glass lens but pairs it with a white LED chip to produce a lighter amber hue, giving you a distinctive look that matches other clear‑lens accessories while still meeting amber‑marker conventions. The glass lens is tempered and features radial prisms that project a crisp star‑burst pattern with no dark voids thanks to the straight PCB design of the AlphaFit bulb.
Dual‑Function AlphaFit G2 LED Bulb (Marker & Signal)
The heart of this light is the new AlphaFit G2 H11‑base bulb. Unlike last generation’s single‑function bulbs, the G2 features a three‑wire harness that provides a low‑power 15 W marker mode and a high‑power 20 W signal mode. You can wire the light as a marker/signal combination or run it at full power continuously—our enlarged anodized‑aluminum body and internal cooling system are designed to handle the heat. Competitor dual‑color lights typically draw just 12 V and override the primary color when the secondary turns on; the G2 lets you choose output levels independently and supports both 12 V and 24 V systems for maximum compatibility.
Advanced Heat Dissipation & Positive‑Pressure Cooling
Borrowing from high‑performance LED headlights, the AlphaFit G2 uses a multi‑stage cooling system. A passive radiator‑fin heat sink and an internal high‑speed fan draw heat away from the LED chip—technology first introduced in the original AlphaFit bulbs. The enlarged anodized‑aluminum body acts as a thermal mass, while four check‑valve vents create a positive‑pressure system that pushes moisture out. This design solves common problems like fogged lenses and condensation that plague cheaper lights.
Real Tempered‑Glass Star Lens & Optimized Beam Pattern
Where many aftermarket lights use plastic or resin lenses, our tempered‑glass housing delivers superior clarity, scratch resistance and a timeless look. The star‑burst lens is precision‑ground to throw sharp, wide beams that travel far and evenly; the AlphaFit bulb’s straight PCB ensures there is no dark center or uneven light distribution. Competitor lights with clear polycarbonate lenses and simple diode arrays can’t match the depth or evenness of our glass‑focused beam.
IP68 Weatherproof Construction & Anodized Aluminum Housing
The Gen 2 housing combines a silicone gasket, sealed anodized‑aluminum base and watertight vent patches to achieve an IP68 rating. Where earlier models were only weather‑resistant, the new seal keeps out moisture under full submersion and operates reliably in rain, snow and wash environments. The anodized aluminum not only looks premium but dissipates heat and resists corrosion better than the plastic or chrome housings found on many competing lights.
Universal Fit & 12/24‑Volt Compatibility
The AlphaFit G2 uses a standard H11 base and includes a color‑coded three‑wire pigtail for easy wiring. It’s plug‑and‑play on both 12‑volt and 24‑volt electrical systems—a major upgrade over competing 12‑volt‑only lights like the Dual Fury and Double Fury kits that use 4‑wire 12‑V hookups. The slim body fits standard watermelon light brackets, cab air cleaners, mirror mounts and other tight spots.
New Color Options & Flexible Customization
In addition to the Amber/White combination, Gen 2 Glass is Class lights are available in Amber/Amber, Clear/Amber, Red/Red, Red/White, Clear/Red and Clear/White. Each combination lets you tailor the beam hue and lens style to your build—whether you want a deep amber marker or a lighter, more neutral glow.
Performance / Compatibility / Use-Case
The Gen 2 Amber/White Glass is Class light is engineered for high‑end show trucks, heavy‑duty rigs and custom pickups that demand bright, even illumination. Traditional dual‑color lights use small diode arrays and produce limited light output. Even premium dual‑color lights deliver 5500 lumens with weather‑resistant housings. Our G2 bulb’s 20 W high‑power mode and glass star lens produce intense, wide beams that rival auxiliary spot lights, yet the 15 W marker setting offers a perfect accent. Because the bulb accepts both 12 V and 24 V power, you can use it on semis, pickups, farm equipment and off‑road builds without adding resistors or voltage converters. The positive‑pressure venting ensures the housing stays dry and clear in humid or cold climates—essential for vehicles that see wide temperature swings.
Installation / Fitment / Technical Details
Installing the Gen 2 light is straightforward. Mount the housing using standard watermelon‑light studs or brackets (sold separately) and connect the three‑wire harness: ground (black), marker/low (blue) and high‑power/signal (yellow). For dual‑function operation, tie the low‑power wire to your running light circuit and the high‑power wire to your turn signal or brake circuit. To run the light at full brightness at all times, simply cap the low‑power wire and connect the high‑power lead to your marker circuit. The light draws 15 W in low mode and 20 W in high mode and operates safely on 12 V or 24 V electrical systems. Thanks to its compact size and H11 base, the light installs cleanly behind air cleaners, on mirror mounts and other tight spaces where older high‑wattage bulbs wouldn’t fit.
Build Quality / Warranty
Every Glass is Class Gen 2 light is built around a real tempered‑glass lens, an anodized‑aluminum body and a fully sealed IP68 enclosure. The internal fan, radiator fins and positive‑pressure venting keep the LED cool and condensation‑free. Our commitment to quality means each light includes a one‑year warranty on materials and workmanship.

Frequently Asked Questions
What’s the difference between the Amber/White and Amber/Amber Gen 2 lights?
The Amber/Amber light uses an amber LED chip behind an amber lens to produce the darkest, richest amber possible. The Amber/White variant combines a white LED chip with an amber lens, creating a slightly lighter amber hue that blends better with clear‑lens accessories and chrome trim. Both variants share the same glass lens, dual‑function AlphaFit G2 bulb and IP68 construction.
Can I run the light on 24‑volt systems or at full power continuously?
Yes. The AlphaFit G2 bulb is designed for both 12 V and 24 V systems and features oversized cooling fins and an internal fan to handle the 20 W high‑power mode. You can run the high‑power circuit continuously without reducing lifespan thanks to the anodized aluminum body and positive‑pressure cooling system.
How does this compare to typical dual‑color watermelon lights?
Most dual‑color lights use plastic lenses and small diode arrays. For example, a Dual Fury light uses 2 amber and 2 white LEDs behind a clear polycarbonate lens and is limited to 12‑volt operation. The Glass is Class Gen 2 features a tempered‑glass lens, a high‑output G2 LED bulb with dual‑function modes, 12/24‑volt compatibility and an IP68 seal—providing brighter, more even light and far better durability.
Are these lights street‑legal?
No. Like the original Glass is Class lights, the Gen 2 series is intended for off‑road and show‑truck use. They are not SAE/DOT approved due to their brightness and beam pattern. Always check local regulations before using them on public roads.
Do I need any special harness or resistors to prevent hyper‑flashing?
The AlphaFit G2 bulb is CAN‑bus friendly and typically does not cause bulb‑out warnings or hyper‑flash thanks to its optimized electronics. However, some vehicles may require load resistors or a flasher module when wiring the high‑power mode into a turn‑signal circuit. Standard H11 harnesses and wiring are compatible.
Can I replace the AlphaFit G2 bulb in the future?
Yes. The bulb uses a standard H11 base and is secured with an O‑ring. Replacement AlphaFit G2 bulbs will be available separately so you can change colors or upgrade when new versions become available. Simply remove the old bulb, insert the new one and reconnect the three‑wire harness.
