This is a replacement turn signal flasher module to eliminate fast turn signal blinking or flashing known as hyperblinking, designed for use with LEDs. This module is specifically for your vehicle. When turn signal bulbs go out, your vehicle's flasher will blink the turn signals quickly to alert you. This is triggered by the lower resistance on the circuit, as the factory bulb is out. When LED turn signal bulbs are installed, it lowers the resistance on the circuit, because LEDs use less power, and you get the fast blinking, known as "hyperblinking," even though the LEDs are functioning just fine. To slow down the blinking, you can add resistors to increase the circuit's power consumption again. However, if possible, replacing the flasher is the easiest option. This is the unit that actually controls the blinking speed, and makes the "clicking" noise. Some newer vehicles have this integrated into the vehicle's computer, so it is not possible to replace it. You will only need one LED flasher for both front and rear LED turn signals.
