hi everyone. so a friend of mine wants me to install an led brake light bar on her 91 ram 350 LE. yes i said her lol. i have a little business out of installin LEDs on ppl vehicles and n this instance she wants the LEDs to be on but dim when the running lights are on. and light up bright when she hits the brake like a brake light. well i am just wondering how i can go about this. the light in the brake lights on either side of the tailgate have 3 wires goin to them. ground constant power and another wire that jumps from .2 volts to .6 volts when the brake is hit. so how could i go about doin what she wants to her truck? i know its gonna b pretty generic but its possible.
