Today I had my car inspected (92 520i, euro spec) , but it failed due to a passenger side parking light (above the headlight) not working, and the reverse lights not working. However, the reverse lights worked for me when I backed out (had the headlights on -- the inspector did not). I assume this is not normal. What would be a cause of this?

Also, how do I get access to the parking light to replace it?
