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!

  • Bulb plugs into a circuit base?
  • Vehicle have blind spot monitoring?
  • Long as its a 4257 base, this bulb will fit
  • Socket Type - 4257

Rest Assured You're Covered

We don't make you ship back the old bulb.We know your time is valuable. We don't want to ask you to waste it driving to the post office. Have a warranty issue?

Super Duty Upgrade

I drive in mainly rural settings where deer, bear and an occasional cow cross the road in front of you. The factory lights just weren’t sufficient. I installed a full set of these lights and the difference is stunning. The visibility improvement is stunning.

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!
