I've added interior lights and at first I had them wired to turn on with the head lights. I did this by tapping into a plug that I think would have been used to power the lights for the gear indicator had it been an automatic. I wanted the lights to come on when the doors open as well. So a little creative wiring and a couple of relays later they do.
The problem is that one of the relays gets it ground from the ground for the factory interior light. Since that ground is controlled by some module and it looses its ground gradually it causes the relay to buzz before it shuts the lights off. I know given time the relay may go out due to fatigue and I don't really care (relays are cheap) but the buzzing sound bugs me.
Is there any way to stop this, could I add a capacitor or is there a electronic relay or should I just put in ear plugs when the lights go out?
