What is LED Turn Signal Hyperflashing and how to fix it

Posted by Kai Sarasch on

LED (light emitting diode) turn signal hyperflashing is a common issue that can occur when LED turn signals are installed on a vehicle that was originally equipped with incandescent bulbs. This is because the electrical system of the vehicle is designed to work with a certain type and load of bulbs, and when LED bulbs are installed, they may draw less current than the system is expecting. As a result, the turn signal relay may not be able to detect the presence of the LED bulbs, causing the turn signals to flash at an abnormally high rate.

To fix LED turn signal hyperflashing, you will need to install a load resistor or LED flasher unit. A load resistor is a small electrical component that is wired in parallel with the LED turn signals and is designed to mimic the load of an incandescent bulb. This tricks the turn signal relay into thinking that the original bulbs are still installed, and the turn signals will flash at the correct rate.

An LED flasher unit is a specialized relay that is designed to work with LED turn signals. It is a direct replacement for the original turn signal relay and is able to properly control the flashing rate of the LED turn signals.

It is important to note that some vehicles may require a specific type of load resistor or LED flasher unit to fix the hyperflashing issue. It is recommended to consult a mechanic or refer to the manufacturer's instructions to determine the correct components to use.
