LumX Reverse 921 (For Rams With Halogen Brake Lights)

Reverse lights 2-3 times brighter than headlights. Most carmakers treat reverse lights as an afterthought, only there to tell people you're backing up. LumX makes them actually useful, so you can see what's behind you.

For Rams with halogen brake lights. Rams with factory LED brake lights use our 7440 version.

Why LumX

• 3,000 lumens per bulb. LumX was the first to put an LED headlight chip in a reverse bulb. A pair puts out 6,000 lumens, about the same as 400 watts of incandescent light.
• Built on 100,000+ sets. We sold over 100,000 sets of the original Lumenex reverse lights, saved every critical review, and fixed every issue. This isn't a small update. It's an entirely new, much-improved bulb.
• Your backup camera sees farther. The most common question we get is whether the extra light washes out the backup camera. With tens of thousands of sets in use, we've never seen it hurt a camera. More light actually lets it see farther and in more detail, like it does in broad daylight.
• Runs cool. The body is milled from a solid block of aluminum to pull heat away from the LED chips, so the bulb runs cooler than a stock halogen while putting out far more light.
• Sealed for any climate. A silicone grommet plus screws around the base seal at least as well as a stock bulb, and dielectric grease comes with every bulb, so you get the full lifespan wherever you live.

Is that too bright?

Maybe. But the extra rear visibility is a real safety feature that can save property and lives, and customers tell us they didn't realize how much they were missing until they installed them.
