I'm in the middle of putting as new stereo system in my 74 and there are several courtesy lights in the console and dash. My question is when I test the lights they work and have power to them but they dont go on. I have tried turning on headlights, interior lights and they don't come on. I also know some become grouned when put into their slot and this should make them work. This is not true with all of them. Can anyone help here???? :smash: :smash: :smash: :smash: :smash: :smash:

The under dash courtesy lights have both a hot wire and ground going into the bulb housing. The bulb needs to be correct with two contacts on the end of the bulb, as the bulb housing doesn't ground itself. Most problems I've encountered with electrical have been due to a bad ground.
Good luck,
Greg

Another possibility to consider is your new stereo. When I installed a new stereo in my 79, it has its own internal alarm wiring into the courtesy lights. Now my vette had the courtesy delay box at the time and I think that is why it got fried. My stereo was detecting that the doors were closed but the courtesy lights were still on. About a week later my courtesy delay box went out. I just bypassed it and had no more problems. Good luck.
