I installed them on the turn signal socket and emergency flash socket. The tail and position lights as well as the turn signals and brake lights had LEDs and did not flash. I've tried everything but there is no flash. So I put a 1157 bulb in the LR taillight and they still didn't flash. So I tried the original turn signal, and both 1157 and front LED flashed normally. When I first tried the new turn signal with the 1157 bulb, I think I heard a short inside the turn signal. So now I have the original turn signals and 1157 bulbs in all four headlights that work perfectly. I don't understand why they don't work! I think the LEDs were wrong. There were 1157 substitutes. UPDATE, THIS SUPPLIER OFFERS A FULL REFUND OR REPLACEMENT! It just doesn't happen anymore. Their customer service goes way beyond what I expected, so this company will back up their products. NO PROBLEM!
