SEALIGHT 921 912 LED Bulbs for Backup Reverse Light, T15 906 904 916 W16W Light Bulbs with Projector Replacement Trunk Cargo 3rd Brake Stop Lights, 600% Brighter Xenon White Non-polarity Pack of 2

I recently upgraded to the SEALIGHT 921 LED Bulb Reverse Lights, and I’m genuinely impressed. The difference in brightness is night and day—literally. These bulbs are incredibly bright, easily living up to the “600% brighter” claim. Backing up at night now feels much safer, with a wider and clearer field of vision. Installation was quick and hassle-free—just plug and play, no special tools or modifications needed. The bulbs fit perfectly into my 921 sockets, and there were no dashboard error codes or flickering issues. The crisp white light also gives my car a more modern look compared to the dull yellow of the stock bulbs. If you’re looking to improve your reverse visibility and add a touch of high-end brightness to your vehicle, these SEALIGHT LEDs are absolutely worth it. Great quality, great value, and a noticeable performance boost.

The SEALIGHT 912/921 LED backup bulbs are an excellent upgrade for any vehicle. They provide super bright, crisp white light that greatly improves visibility when reversing, making parking safer and easier. Installation is simple, thanks to their plug-and-play design with non-polarity and CANbus error-free technology, ensuring no flickering or dashboard warnings on most cars. These bulbs are built with durable aircraft-grade aluminum for fast heat dissipation and long life, rated up to 30,000 to 50,000 hours. They’re waterproof and reliable, making them a great value for anyone wanting brighter, more modern backup lights. Highly recommended!

A definite must-have if you are currently using OEM lamps. These lamps are exceptionally bright—bright enough that the difference is noticeable even in broad daylight. If you install just one and put the vehicle in reverse, the contrast between the new lamp and the OEM lamp is immediately obvious. I’ve only just installed them, so I cannot yet comment on long-term durability. However, they appear to be well constructed, with a high number of small LED chips densely arranged inside the housing. The illumination includes both wide-angle and narrow-angle (spot) coverage, whereas many alternatives provide only wide-angle light and fail to clearly illuminate the area directly behind the vehicle. The lamps fit perfectly with no issues during installation. Overall, these lamps easily earn four stars. The only reason I did not rate them five stars is that I am not convinced they are 600 times brighter as advertised. It would be helpful to have quantifiable data—such as candlepower or lumen ratings—for a more accurate comparison to OEM lamps. That said, they remain an excellent upgrade and a definite must-have if you are still using OEM lighting.

Nice and bright

Stupid bright for my reverse lights big difference then the halogens. Can't wait to see how bright these are when I'm backing up. I could see how bright they are when I was testing them in daylight.
