Kenworth Cabover LED Headlights

Frequently Asked Questions About Kenworth Cabover LED Headlights

Will these LED headlights fit my specific Kenworth cabover model and year?

Our Kenworth cabover LED headlights are designed to fit K100, K100E, W900B, and most cabover models from 1961-1990. However, some mid-80s models with aerodynamic packages may require different mounting brackets. We recommend checking your existing headlight housing dimensions (typically 7" round or 5x7" rectangular) before ordering. If you're unsure about compatibility, contact us with your OEM or model year for verification.

Do I need to modify my wiring or add resistors when installing LED headlights?

Most of our LED headlights are plug-and-play replacements that work with your existing wiring harness. However, some older Kenworth cabovers (pre-1975) may require a polarity adapter or relay upgrade to prevent flickering. LED headlights draw less power than halogens, so you won't need load resistors, but we do recommend checking your ground connections and ensuring your alternator produces at least 13.5 volts for optimal performance.

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

Installation typically takes 30-45 minutes per headlight. You'll need basic hand tools including Phillips and flathead screwdrivers, and possibly a 10mm socket for headlight ring removal. The most challenging part is often accessing the back of the headlight housing in tight cabover engine compartments. Many customers find it easier to remove the entire headlight bucket assembly first. Detailed instructions are included with each set.

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

Our LED headlights typically produce 3,000-4,500 lumens per light compared to 700-1,000 lumens from original sealed beams. This translates to approximately 300% more usable light on the road. The beam pattern is DOT-approved with a proper cutoff line to prevent blinding oncoming traffic. Most drivers report significantly improved visibility at highway speeds, especially in rural areas without street lighting.

How long do these LED headlights actually last, and what's covered under warranty?

Quality LED headlights are rated for 30,000-50,000 hours of continuous use, which typically translates to 10-15 years of normal driving. They're built with die-cast aluminum housings and polycarbonate lenses that resist vibration damage common in cabover applications. Most units carry a 2-3 year warranty covering defects and premature LED failure. Note that physical damage from road debris or improper installation typically isn't covered.
