Review on 🔦 Alla Lighting T10/T15 912 921 W16W LED Reverse Light Bulb: Error-Free, 6000K White Back-Up/Trunk/3rd Brake Lights Lamp Upgrade – CAN-BUS Compatible by Sri Mims

Attention! Before buying I read other reviews and saw that some people had the same problem. In my opinion, if you're not experienced with small electronics, ditch them and maybe spend a buck or two more. A common problem with these lamps is poor soldering of the components. It looks like it ends up with solder bridges that short out when plugged in, giving off lots of heat and smoke. Examine these bulbs carefully before attempting to use them, or have extra backups on hand and send the bulbs back. When I first took them out of the box I saw that one of my lamps had two solder bridges (first two pictures) and the other didn't. I took my soldering iron and shook off the excess solder (third photo), and the light worked. I've been running them for the past two weeks with no issues other than this one. If you inspect them first and have a soldering iron, they are generally solid and very bright.
