    Hello guys! I'm adding LEDs to the interior of my car, it comes in an RDG strip and I plan to wire them to the Dome welcome lights AND to the headlights so the also work as ambient lights in the night, I know which fuses to tap BUT I need to wire a Bosch Relay to work as an or gate, this is what I have in mind but I'm not sure (I'm a noob)

    30: Led Strip
    85: Ground (derp)
    86: Headlight fuse
    87: Constant 12v
    87a: Dome Light

    This way, when the headlights are ON the coil is activated and the gate lowers to 87 which is constant 12v, so the LEDs will always be ON, else the gate will be on 87a and will only power the LEDs when the Dome Lights are ON (doors open)

    So what do you think, will this work?

    P.S: I have 5 Bosch Relays, but my life would be so much easier if I could only use one, thanks.

    Thanks! However, I want to make sure it WILL work, I don't want to blow up a $33 LED strip especially how difficult it was for me to get it (I don;t live in the US)

    This is a diagram of how the relay works just in case
