Freightliner Cabover LED Headlights

Frequently Asked Questions About Freightliner FLT Cabover LED Headlights

Will these LED headlights fit my specific FLT model year?

Our LED headlights are designed to fit Freightliner FLT cabover models from 1984 through 1995, including the FLT 86, FLT 112, and FLT 120 series. They use the standard 7-inch round housing and will directly replace your original sealed beam headlights. However, models with quad headlight setups may require additional mounting brackets. Always verify your truck's headlight configuration before ordering.

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

Most of our LED headlights feature standard H4 3-prong connectors that plug directly into your existing wiring harness. However, some older FLT models (pre-1987) may require an H4 conversion harness, which we sell separately. The LEDs draw less power than traditional sealed beams, so no relay upgrades are needed. Installation typically takes 30-45 minutes per side with basic hand tools.

How much brighter are these LEDs compared to stock halogen headlights?

Our LED headlights produce between 3,600-4,800 lumens per light, which is approximately 200-300% brighter than standard halogen sealed beams. The focused beam pattern provides better road visibility without blinding oncoming traffic. Most drivers report significantly improved nighttime visibility, especially in rural areas without street lighting.

Are these DOT approved and legal for street use?

Yes, all LED headlights in this category are DOT approved and SAE compliant for street use in all 50 states. Each light features the required DOT marking on the lens. They meet or exceed FMVSS 108 standards for beam pattern, intensity, and cut-off requirements. We recommend keeping your purchase receipt as proof of compliance for inspections.

What's the actual lifespan of these LED headlights in real-world trucking conditions?

Our LED headlights are rated for 50,000+ hours of operation, which typically translates to 8-10 years of commercial use. They feature aluminum housings with built-in heat sinks and are sealed to IP67 standards for water and dust resistance. The solid-state design handles vibration better than traditional bulbs. We offer a 2-year warranty, but most customers report trouble-free operation well beyond that period.
