Review on 🔘 AUXLIGHT 921 912 906 904 T15 W16W High Power Error-Free Back Up Reverse Brake Light Bulbs - Pack of 4 (White/Red) by Brian Price

** Both truck lights could not be updated with an interval of several days. I assume they are not dimmable and my truck has a "fade out" feature which it uses to turn off the cargo and dome lights. Reversing lights still work 100%. **I bought a used truck and the backup lights and truck headlights are tired so I decided to replace them with LEDs immediately. both were 912s. A good choice as my truck headlights are as bright as the lights in my garage I don't need a flashlight to see or work on the back of my truck. Even after a few minutes it doesn't get as hot as the old headlights. The reversing lights themselves are bright, even without reflectors. I can see much better from the side as the LEDs face outwards and I don't rely on a reflector to direct the light sideways. There are no more shadows and the picture from my rear view camera is now as bright as day. If you live in the woods and not in the city they are great, no extra light pods needed. The only downside is that they are longer than the factory bulbs, but that wasn't a problem on my truck. Also, the sockets on the side of the truck had ribs to support the lamps that disrupted the placement of the LED lamps, offsetting them from the center but easily fixed with a knife in a matter of seconds. Be sure to check the tolerances in your application.
