Alla Lighting 912 921 LED Bulbs for Back-up Reverse Lights, 6000K Xenon White CAN-BUS 4014 30-SMD T10 T15 906 W16W 921K 922, 360° Light Backup, Cargo Lights Replacement, Extremely Super Bright

Brighter, and whiter, than the dim/yellowish incandescent OEM bulbs that came in my 2024 GM Pickup.That said these are on the low end of brightness available from modern LED replacement bulbs.I upgraded my ALLA back up lights to better LEDs, and then move these to the cargo light on the back of my cab. These are good LEDs, and I’ve had good luck with them, but they are much less bright than the current state of the art.

I highly recommend these for your car. I use an Infiniti G 37X and it fit perfectly and it's very bright for backing up. The nicest thing is that it brightens up for the backing up camera.

This brand has proven to be long-lasting and reliable. I replaced all the factory incandescent bulbs in our three vehicles and two trailers with this brand's LED equivalents. They've held up well with zero failures. Some have been in for five years or more, so I'd definitely buy them again.

I can actually see where I’m going while in reverse and in the dark. Bright as 6000 kelvin headlights

These have been pretty good backup lights in our '09 Subie Outback. They give considerably better* illumination than the original incandescent bulbs. There is lots of room in the '09 Outback's backup light housing for these to dissipate heat, and we've had no problems with that, there.HOWEVER, even at only 5.5 watts per bulb, these run too hot in the cargo light housing, and can kill themselves with self-heating if the cargo light is left on for long on a hot summer night. Said housing is very "tight" and allows for little heat sinking / dissipation. I've actually pulled it out and am completely reworking it for a wafer type light I can heat sink to the rear. So, word to the wise, if your backup light housing is sort of tight to the bulb and doesn't allow for enough heat dissipation, most any really bright LED light you put in there may kill itself or become intermittent.OTOH, if there is a lot of room and / or good air circulation, you may be able to go to higher wattage / light output. Ratings of 1500 lumens per bulb or even a bit higher are not uncommon. (Said ratings may or may not be legit -- in fact I question if these are really 1000 lumens.)If you need even more light, or light for more than maybe a minute at a time, the best bet is to go with a light with a metal housing, mounted completely separately, and likely switched separately, too. Those, if well designed and manufactured, are better suited to handle the heat buildup of being on for over a minute.*A last thought: Color temperatures of 5000k and over, while making for "crisp" illumination, are NOT eye-friendly to other drivers, and if glaring at them might even cause a collision. It would be nice to see these at a compromise color temperature, say, 4000K.

Works great. Only thing to know is they will make your blinker flash faster. Not a problem.

I would say the bulbs are great on brightness but not can-bus error free in my Audi. They are very bright for my reverse lights, but did throw an error. I would say give them a shot but I did have to code out the error in my Audi. I’m pleased on them. Just slight modding needed.

These are extremely bright, you will have to adjust the settings on your backup camera for night time but I'm very happy. Let's see how long they last.
