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 Paul Opoku

They are really bright and beautiful. Strobe If you hold the brakes a lot, to put it mildly, they will flash 4-5 times and each time the strobe will be 3 times faster each time. That means they blink a total of 15 times. It seems overkill, but it only happens when you hold the brake pedal. If you press the brake pedal quickly, it will only flash once (or three times quickly) depending on how long you hold the brake pedal down. You would have to be blind now to see that. But there is also cause for concern about seizures in people behind you.
