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!

Dieselleds are great!!

Updated the Jeep JL reverse lights to Dieselleds. Huge difference, much brighter, now easier to see backing up the trailer!

Unbelievable brightness for reverse lights, pricey but well worth it

Broken Record

It’s been said over and over. Headlights for backing up. Have them on my Silverado and now my Wrangler. Money well spent.
