Rally happy with the ease and utility of installation. I’ve read reviews about these lights “staying on” when the vehicle is off. Simply, that’s an issue with the installer. They don’t have batteries. They’re not solar powered. If they’re staying on, you wired them incorrectly. They are basic led lights with a very user friendly wiring system that comes with everything needed to easily install them and have them working perfectly. I did use a heat gun on the adhesive strips and also the grille where I mounted them. I held them in place for 30 seconds. They fire up and die with the chosen fuse I used. Look great. Easy installation. 30 minutes total. Couldn’t be happier with the easy connections that the manufacturer provided. The wiring harness is easy to understand. They provided jumpers to add into the fuse box. The lights, individually, disconnect from the harness so that mounting each one, and reconnection is very easy.
