Here's one I picked up living in upstate NY and forgot about after moving back to Kansas. Picked up this 97 Bonneville about a year ago. One of the backup lamps recently burned out and I went to replace it. Well, shades of NY State (and some other places I imagine), guess I'm not immune.
As this was an aftermarket socket, the problem isn't uncommon. What was uncommon was the cheapest new socket I could find was $27, some wanting $52. Good ol junk yard came to the rescue. 5 bucks ea so I bought both, the other one was getting junked up to.
All I do is put a thin coating of antiseize on the brass base, be careful not to get any on the ceramic or the contact point on the bottom of the bulb. The stuff is a conductor and will short out the circuit
