The Diode Dynamics LED relay Flasher Fix for
the FRS and BRZ.
This is a replacement turn signal flasher module. It will eliminate fast
turn signal blinking, known as hyperblinking, that occurs when you
replace your turn signal bulbs with LEDs. It has been designed
specifically for use with LEDs.
This module is specifically for your vehicle! It will be 100% plug and
play. Just remove the factory flasher, and plug this one in.
Why do you need this module? When your factory turn signal bulbs go out,
your vehicle's flasher senses that less power is being used, and it will
blink the turn signals quickly to alert you. When LED turn signal bulbs
are installed, it lowers the load on the circuit too, because LEDs use
less power. You get the fast blinking, known as "hyperblinking," even
though the LEDs are functioning just fine. Basically, your car thinks
the bulbs went out!
To slow down the blinking to regular speed, you can add resistors to
increase the circuit's power consumption again. However, whenever
possible, replacing the flasher with a module like this is the easiest
option. This is the unit that actually controls the blinking speed, and
makes the "clicking" noise.
