Here, you are looking at the OLM LED Hyperblink Module. With the latest in LED technology in current vehicles or with aftermarket lighting, LEDs will have less of a current draw than the halogen bulbs they replace. This will cause the turn signals to "hyperblink", or blink really fast. OLM has a plug and play solution that will prevent fast blinking.

If you switch out any of your factory signal bulbs to LED bulbs you will get a fast flashing signal. This happens because when you use an LED bulb it has far less resistance than a standard bulb so your vehicle receives a signal that the bulb is burnt out even though the LED bulb is working as it should. The fast blinking is just to let you know a bulb is out. To fix the hyper-flashing you can install an in-line resistor but the easiest and most efficient way is to install our flasher relay. Simply unplug the factory relay located under the driver's side dash and plug our relay in and the flashing will be back to normal.
