Used when you wish to control your auxiliary light, LED lightbar or similar together with the high beam and the car only supplies a current pulse to start the high beam and not a constant current (if you have a combined xenon lamp for high and low beam).
Connects according to separate diagram (let us know which car it will be fitted to via message at checkout).
Follow the instructions carefully, if you are unsure - contact us or ask a workshop.
