Kenworth Lighting

Frequently Asked Questions About Kenworth Lighting

What model years are your Kenworth lights compatible with?

Our Kenworth lighting products are designed to fit T680 models from 2013-present, T880 models from 2014-present, W900 models from 2008-present, and T800 models from 2008-2019. Always check the specific product description for exact fitment details, as some lights are model-specific. For example, our LED headlights for the T680 require different mounting brackets than those for the W900.

Do I need special tools or wiring modifications to install LED lights on my Kenworth?

Most of our Kenworth LED lights are designed as direct plug-and-play replacements using existing factory connectors. Basic hand tools like screwdrivers and socket wrenches are typically all you need. However, some aftermarket auxiliary lights may require drilling mounting holes and running new wiring. We recommend having wire crimpers, electrical tape, and a test light on hand. Installation usually takes 30-60 minutes per light assembly.

What's the difference between DOT-approved and off-road LED lights for Kenworth trucks?

DOT-approved lights meet federal safety standards for on-highway use and include proper beam patterns, brightness levels, and color temperatures (typically 3000K-5000K for headlights). Off-road lights often feature higher lumen outputs and different beam patterns but cannot legally be used on public roads. All our headlights, tail lights, and turn signals are DOT-compliant. Light bars and auxiliary pods are typically marked for off-road use only.

How do chrome, black, and clear lens options affect light output and appearance?

Chrome bezels provide the classic Kenworth look and don't affect light output. Black bezels offer a modern, aggressive appearance and are powder-coated for durability. Clear lenses typically provide 10-15% more light output than smoked lenses, which reduce output but create a custom appearance. Smoked lenses are legal for marker lights but check local regulations for headlight and tail light applications.

Will LED lights cause error messages or hyperflashing on my Kenworth?

Some Kenworth models from 2016 and newer may display dashboard warnings when switching to LED lights due to the lower power draw. This is especially common with turn signals, which may hyperflash. We offer load resistors and flasher relays specifically designed for Kenworth trucks to eliminate these issues. The resistors wire inline with your turn signals, while updated flasher relays are direct replacements for the factory unit under the dash.
