I just fixed the dome light on my P4 coupe. Lens just popped of with no problem ( just a slight squeeze on sides of lens). Bulb checked out OK, so I removed the On/Off switch. The wire connections were GREEN. I had an extra switch so I cleaned the bare ends of the wires and installed the new switch. Worked perfectly. In fact, my dome light seems brighter than my head lights.  :D

need to check / replace bulb.? any secrets to removing the bezel & lens or can I just pry it loose carefully?
thanks,
