Digi-Tails Brake Light Pulsers

Digi-Tails brake light pulsers are intended for use with your third brake light. The pulser connects inline with the brake light signal and causes the light to pulse several times before remaining on steady. However, if you are adding a third brake light to your vehicle and you don't have a brake signal, you can either run a brake signal off of the brake switch, or you can use a Digi-Tails taillight signal separator (sold separately).
