power car headlamp with LED as home decoration lamp?
I have this Audi A4 Lamp with LED DRL, I want to power the LED up at home as decoration.Opened the headlamp housing, and trace the wire, I found the led strip has 4 wires, and I don't know which is (+) which is (-), I did some internet search of 4 pin led strip, and most of the info was RGB led. I don't believe this Audi LED DRL has RGB. tried (+ + - -) (+ - - +) (- + + -) with no luck.
any advice to power the LED up at home?
