Compare Peterbilt 389 replacement headlights, LED bulb kits and heated LED assemblies, plus rear housing covers and wiring accessories. Choose by the equipment currently installed, listed application and required side.
Explore factory-style, chrome and blackout options. Check the bulb type, housing clearance, wiring and package contents for each product, or use our Peterbilt 389 headlight testing guide to compare beam patterns and measured output.
See BTS Lighting’s comparison of halogen headlights, LED assemblies, heated LED headlights and an Alpha Series bulb upgrade. Review lux readings alongside beam-pattern notes and the tested setup; results are a comparison under those test conditions, not a guarantee for every installation.
Start with the job: replace a worn housing, compare a complete lighting assembly, service compatible bulbs, or add a supporting accessory. The installed equipment, wiring and condition of the truck determine which options to compare.
Start with the housing condition. Cloudy, cracked, leaking or damaged headlights may need an assembly replacement before considering a bulb change. Match the listed application, mounting points, connections and selected side to your truck.
Compare the main beam’s light source separately from any LED light bar, position light or turn signal. Chrome, blackout and projection styling describe different features; check the exact assembly for included lighting components, wiring and application details.
A bulb kit keeps the existing housing, so confirm its bulb specification, condition and rear clearance. The Alpha Series ReadyFit 389 kit is listed for compatible original factory halogen headlights using H11 low beams and 9005 high beams. Follow its guide for extended low-beam caps and the warning check that determines whether the included high-beam modules are needed.
The collection includes JW Speaker 9600 heated LED options. Compare the exact application, selected side and harness requirements. A bulb’s cooling fan or heat sink is different from a heated headlight lens; choose the feature stated for the complete product.
Rear headlight housing covers and wiring harnesses are supporting parts, not complete replacement headlights. Match them to the specific housing or headlight system and review the supplied quantity.
Brightness is only one part of the comparison. Beam pattern, aim, lens condition, wiring and optical design all affect the finished installation. A brighter bulb will not repair a cracked or leaking housing, and scattered or incorrectly aimed light can undermine the result.
Compare the guide’s lux readings and beam-pattern notes together, then follow the exact product’s installation and aiming instructions. Confirm the listed road-use and application restrictions for the selected setup.
Peterbilt 389 headlight fitment depends on the exact product, year range, side, wiring, and headlight style. Always check the individual product listing before ordering because compatibility can vary by SKU/model.
LED headlights can be better than halogen when they are properly matched to the truck, housing, wiring, and intended use. A good LED setup can improve visibility and style, but beam pattern, aim, and compatibility matter as much as brightness.
Replace the full assembly if your current headlight housing is cracked, cloudy, leaking, or damaged. Consider LED bulbs if your existing housings are clean, sealed, compatible, and in good condition.
Some Peterbilt 389 headlights may include bulbs or lighting components, while others may not. Included parts vary by SKU/model, so check the product listing to confirm what comes in the box before ordering.
Peterbilt 389 headlights may be sold individually, as driver side or passenger side, as pairs, or as kits depending on the product. Check the exact listing title and product details before adding to cart.
Some Peterbilt 389 LED headlight upgrades may require wiring accessories, adapters, harnesses, decoders, or modules. Requirements vary by SKU/model and truck setup, so review the listing or contact BTS Lighting to confirm.
Replacement headlights are mainly used to repair or refresh worn assemblies, while LED upgrades are chosen to improve output, appearance, or functionality. Some products do both, but the right choice depends on your current headlight condition and upgrade goals.
Yes, heated LED headlight options are available for Peterbilt 389 applications. These are often chosen by drivers who operate in cold, snowy, icy, or wet conditions where heated lens technology may be useful.
Confirm bulb size by checking your current headlight assembly, old bulb markings, or the exact product listing. Bulb size can vary between factory-style housings, aftermarket assemblies, and previous modifications.
You can compare Peterbilt 389 headlight options in our testing guide, which reviews halogen, LED assembly, heated LED, and LED bulb upgrade choices using lux readings and beam-pattern notes.
