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
  • Cooling Method - LED's cooled by electric fan mounted on top of bulb

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?

Great upgrade!

I originally bought a set of these reverse lights in 2021 for my truck and was absolutely in love with them. One of my lights was starting to short out so Diesel LEDs offered me an upgrade on a new set of reverse lights. I noticed an increase in usable light from the previous generation to the new reverse lights. Would highly recommend anybody looking to increase their backup lighting output

Reverse lights

Purchased the reverse lights illuminates really well makes it really easy to reverse in the dark and goes a long way. Also the 3rd brake light and cargo lights makes loading late loads a ease and having to work. Worked great on my 2016 GMC
