I installed the led tail lights from AM and they were blinking as if there was a bulb out. The box didn't have a relay in it so I contacted AM and they sent a new one. Once installed the left signal would hesitate before signaling like normal. The right side would blink extremely slowly. Contacted AM and sent a new one out as it may have been faulty. Got it installed today and there isn't a change in speed. I installed the resistors as well.
