Review on 🚦 AUXLIGHT 7440 7441 7443 7444 T20 992 W21W LED Strobe Bulbs: Brilliant Red, Ultra Bright 57-SMD LED Brake/Tail/Stop Lights Replacement (Pack of 2) by Shedrick Roach

Very bright. They will flash 5 times before turning on steadily for the brakes. If your brake light and turn signals use the same bulb, THIS IS NOT SUITABLE FOR YOU! EVERY TIME YOUR TURN SIGNAL FLASHES THE 5 TIMER STROBE WILL BE RESET. You will be paused and ticked off. That being said, if it's just for the brakes, that's great. I spoke to the local police and they said it was fine if it stopped after 5. *Upgraded to 1 star. The strobe function no longer works and the brake function is now permanently on, giving the impression that the brakes are stuck. Not even a few months in use.
