Just installed my tap turn relay with my Tom's tail lights and front turn signal LEDs. Very pleased with the results. No lag when you engage the switch and the flash is a distinct on and off. I wrapped some foam weatherstripping around it to cut down on the noise. I played around with the settings to give me 4 flashes on the lane change function and 24 seconds of delay before the lights go off when I lock it. Pretty cool feature as I can tell that I locked the car when I walk away in the parking garage at work. I always turn around and look at the car as I walk away.
