Freightliner FLC120 LED Headlights

Frequently Asked Questions About Freightliner FLC120 LED Headlights

Will these LED headlights fit my specific year FLC120?

Our LED headlights are designed to fit Freightliner FLC120 models from 1988 through 2002. They use the standard 7-inch round housing that comes factory-installed on all FLC120 trucks during these production years. The mounting points and electrical connections remain consistent across these model years, ensuring a direct replacement fit without modifications.

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

Most of our FLC120 LED headlights feature plug-and-play installation with H4 connectors that match your truck's existing wiring harness. However, some older models (pre-1990) may require an H4 to sealed beam adapter, which we offer separately. No cutting or splicing of wires is necessary. The LEDs are designed to work with your truck's standard 12-24V electrical system without requiring additional relays or resistors.

What's the actual light output difference compared to my stock halogen headlights?

Our LED headlights typically produce 3,000-4,500 lumens per light, compared to the 1,000-1,500 lumens of standard halogen sealed beams. This translates to approximately 200-300% more usable light on the road. The beam pattern is DOT-compliant with a proper cutoff line to prevent blinding oncoming traffic while providing significantly improved visibility at distances of 500+ feet.

How durable are these LED headlights in harsh weather and road conditions?

These headlights feature IP67 waterproof ratings, meaning they're completely sealed against dust and can withstand water immersion up to 1 meter. The polycarbonate lenses resist cracking from stone chips better than glass sealed beams. The aluminum housing dissipates heat effectively, preventing LED degradation. Most units carry a 2-3 year warranty and are tested to last 50,000+ hours of operation in extreme temperatures from -40F to 185F.

What style options are available, and will they match my truck's appearance?

We offer several styles including classic round with chrome or black bezels, modern projector-style with angel eye halos, and traditional sealed beam appearance with LED internals. Most feature clear lenses for maximum light output, though some models offer ice-blue or amber accent lighting. The 7-inch round format maintains your FLC120's original appearance while providing modern lighting performance. Chrome options match factory bumpers and mirrors, while black housings complement custom or murdered-out builds.
