Will NOT work on Super Dutys with OEM LED Tail Lights

Fan Cooled Technology in a replacement bulb!

(Sold as set of 2 Bulbs)

LumX has been pushing the boundaries of what is possible when it comes to external LED bulbs. While other manufacturers focus on headlight bulbs, we're trying to create extremely bright, efficient replacement bulbs for other applications.

The LumX FC series is the latest example of this push. We packed 50 separate EMC LED chips onto this one bulb! This creates a staggering 2000 Lumens PER BULB! This would not be possible without an efficient cooling method. For this we designed, from what we've seen, to be one of the first reverse lights with a built-in electronic fan to cool the bulb!

There are certain applications where our normal heat sink cooled reverse light set will not work. For those applications we've created the FC series! "Fan Cooled"

 

This creates an extremely universal bulb that will work on any application where the socket fits!

  • Vehicle have blind spot monitoring?
  • Long as its a 4257 base, this bulb will fit

Very bright reversing lights

I have a 2022 ford f350 dually and the factory bulbs are considerably dim. I recently tinted my front driver and passenger windows to 20% tint to match my factory rear windows and it made it even harder to see when backing up. I had to roll my window down in order to see in my side mirrors.
Fast forward to installing these led bulbs and now I can see to back up while looking through the tinted windows. The bulbs are a little pricey but so worth it now that I can see!

SUPER BRIGHT

Had a little difficulty installing the new LED reverse bulbs, little more pressure to insert bulb into factory socket than expected, but fit and works brighter than expected. No need to mount auxiliary lights to see when backing up.
