Customer Reviews

Bright AF, need some force to seat into bulb hole.

The bulbs are bright, much brighter than any T10 or 921 bulb that many use for Japanese cars. Biggest issue is fitment, you really need to shove the bulb in and hope it seats itself even with the o-ring. I would really recommended taking the light unit out to give yourself more leverage and balance as you'll need it to get the light bulb in. Once it's in and the unit is bolted back on the car, it should be secured.

Exceeds my expectations

Wow, these are bright!

Daniel T.O.

Definitely brighter reverse lights in my 2017 Silverado. Shown here on the driver side. Stoxk lamps in the passenger side.

Bright Reverse Lights

Super bright lights and pretty easy to install. I would buy them again.

Donnie T. (United States)
Backup Reverse lights

I purchased these lights for my girlfriend's SUV because the factory bulbs were no help; the factory rear window tent is pretty dark. However, the installation was straightforward, and the bulbs were better than I expected. In addition, she could see perfectly with the new bulbs, so I no longer worry about her backing up after dark. As always with Alla, the company, the shipping was swift, and the staff is more than willing to help.
