I am currently trying to re design the rear lights on a car with leds. The car currently uses bay15d bulbs which are used as sidelights and brake lights So have 3 wires (I'm guessing 2 positive and 1 negative). I want to wire in a circuit of leds inside the unit that come on with the sidelights and go brighter with the brakes, how would i go about wiring them in to the cars wiring ?
any help is much appreciated
thanks
