Power that goes on and off with the headlights

BMWjames · 07-07-2010, 11:18 AM

I need a 12v source some where in the interior that only has power when the headlights are on. Is there a fuse that does this?

Sorry in advance if this is the wrong section, mods please move this if that is the case.

I remember seeing someone who hooked it up to the button for the trunk

I use the 12v cigg lighter in my armrest to power my angel eyes as Daytime running lights. Its switched eith the acc power meaning that it goes on after clicking the start button twice, no foot on brake. You can also use the cigg lighter by the as tray.

Wait my source is on all the time though...what are you trying to do? You could wire a switch in.

I am just straight up dumb when it comes to this stuff.... but what I want to do is wire in LEDs to the arm rest and a few other places. I don't want them to be on all the time though, only when the dash lights come on when the headlights come on. I guess a switch would work as well but then I have to mount it some place.

Also has anyone found LEDs that match the OEM amber/orange dash lighting?
