Will these LED headlights fit my specific year Kenworth W900B or W900L?
Our LED headlights are designed to fit Kenworth W900B models from 1987-2017 and W900L models from 1987-2010 that use dual rectangular headlight configurations. These are direct replacements for the standard 4x6 inch rectangular sealed beam headlights. If your truck has been modified with custom headlight buckets or aftermarket grilles, we recommend measuring your current headlight dimensions before ordering to ensure proper fitment.
Do I need any special wiring or adapters to install these LED headlights?
Most of our LED headlights are plug-and-play with the standard H4656 or H4651 connectors found in W900B and W900L models. No cutting or splicing is required. However, some older trucks (pre-1990) may need an H4 to H4656 adapter plug, which we sell separately. If your truck has daytime running lights, you may need to install a load resistor to prevent hyperflashing or error messages on your dash.
How much brighter are LED headlights compared to my stock halogen bulbs?
Our LED headlights typically produce 3-4 times more lumens than standard halogen sealed beams, with most units offering between 3,000-4,500 lumens per light. This translates to approximately 200-300% brighter illumination with a cleaner, whiter light output (5,000K-6,000K color temperature) compared to the yellowish 3,200K of halogens. The focused beam pattern also provides better road coverage without blinding oncoming traffic when properly aimed.
Are these LED headlights DOT approved and legal for street use?
Yes, all LED headlights we carry for the W900B/W900L are DOT approved and SAE certified for on-road use in all 50 states. Each light is stamped with DOT compliance markings. They feature proper high/low beam patterns that meet FMVSS-108 requirements. We recommend having your headlights professionally aimed after installation to ensure they meet local inspection requirements and provide optimal visibility.
What's the typical lifespan of these LED headlights, and do they come with a warranty?
Quality LED headlights typically last 30,000-50,000 hours of operation, which translates to approximately 15-20 years of normal truck use. This is significantly longer than halogen bulbs that need replacement every 1-2 years. Most manufacturers we carry offer warranties ranging from 1-3 years against defects. The aluminum housing and polycarbonate lenses are also more resistant to vibration damage compared to glass sealed beams, making them ideal for long-haul applications.
