⚠ Will NOT work on Super Duty trucks with factory LED tail lights.
Fan-cooled power in a replacement bulb. Sold as a set of 2 bulbs.
Why LumX-FC
-
2,000 lumens per bulb. We packed 50 separate EMC LED chips onto one bulb. That output isn't possible without serious cooling, so this is one of the first reverse lights with a built-in electric fan.
-
Works where our heat-sink reverse set won't. Some housings don't fit our standard LumX reverse set, so we made the FC ("Fan Cooled") series for them.
-
Fits almost anywhere. Bulb plugs into a circuit board? Vehicle has blind-spot monitoring? As long as it's a 4257 socket, this bulb will fit.
