Installing new LED front turn signal bulbs on the Duramax and bulb load resistors to fix the fast flashing issue. According to our bulb guide, you vehicle does not have a replaceable flasher. This happens because your new LED bulbs draw such little power that your turn signal relay sees the bulbs as being out. Reasons for LED floodlight flashing on/off. Our LED flashers function with both LED and incandescent bulbs, so even if you have LED turn signals in the back and incandescent bulbs still in the front, you can use our LED flasher modules with no problems. Unfortunately, we do not have any cross reference information to tell what flasher you would need to replace your stock flasher. This brings us to our last solution to the hyper-flashing issue. In addition to that, most of these are designed using a 3 ohm resistor instead since they will be in direct proximity to the pre- wired wires to prevent overheating and melting. The reason the turn signals quit working when the lights are on, is that a 12-volt signal is now being sent down the opposite wire, which was acting as a ground before. Okay, I’ve been reading all this posts and realize relays or resistors are required to stop hyper flash. In most cases, these flasher units are little circular or square boxes with metal prongs sticking out one side that simply plug into where your stock flasher went. 4 Ways To Get Rid of Hyper-Flashing With LED Turn Signal Bulbs! Help! When the headlights are on, the brake lights, running lights, back-up lights all function as expected.
