Hi, I'm new to this site and have been thinking about installing lights behind my ac vents for an accent light. I would be using a 12 volt white automotive bulb, drilling a small hole behind the vents and running it to a switch so that it can be turned on and off. I was wondering if anyone has done this before and if anyone thought that the hot or cold air would effect the bulb. I saw this done in a Grand Am and have been thinking about trying it on my X.
