Frequently Asked Questions About Kenworth T800 LED Headlights

What year models of Kenworth T800 are these LED headlights compatible with?

Our LED headlights are designed to fit Kenworth T800 trucks from 1987 to 2010. The headlights use standard 7-inch round or 5x7 rectangular mounting patterns depending on your specific model year. Pre-1997 models typically use the 7-inch round style, while 1997-2010 models commonly use the 5x7 rectangular pattern. Always verify your truck's headlight size and mounting style before ordering.

Do I need any special wiring or adapters to install these LED headlights?

Most of our LED headlights are plug-and-play replacements that connect directly to your existing H4 headlight connectors. However, some older T800 models may require an H4 to H6054 adapter harness, which we sell separately. Additionally, certain LED models may trigger a "bulb out" warning on your dash, which can be resolved with an anti-flicker harness or load resistor kit.

How difficult is the installation process and what tools do I need?

Installation typically takes 30-45 minutes per side and requires basic hand tools including a Phillips screwdriver, socket wrench set, and possibly trim removal tools. You'll need to remove the grille and headlight bezels, disconnect the old sealed beam units, and install the new LED assemblies. No cutting or drilling is required. We recommend having dielectric grease on hand for the electrical connections to prevent corrosion.

What's the actual brightness difference compared to stock halogen headlights?

Our LED headlights typically produce 3,000-6,000 lumens per light compared to 700-1,000 lumens from standard halogen sealed beams. This translates to approximately 300-400% more usable light on the road. The crisp white light (5000K-6000K color temperature) provides better visibility in rain, fog, and dark conditions while reducing eye strain during long hauls.

Are these DOT approved and legal for highway use?

Yes, all LED headlights we carry for the Kenworth T800 are DOT approved and SAE compliant for legal road use in all 50 states. Each light is stamped with DOT certification markings. They feature proper beam patterns that won't blind oncoming traffic and meet or exceed all federal lighting standards. We only stock quality brands that have undergone rigorous testing for commercial vehicle applications.
