My bright lights aren't working and my car is due for an inspection this month, which I've been told the car won't pass because of the lights. Before I spend $130 getting the problem diagnosed, I was wondering if anyone could tell me what would cause this to happen. I don't believe both bulbs are out because it seems unlikely that they'd go out at the same time. I'm thinking it's a connection problem because the lights came on once after the problem started. Any ideas?

Thanks for your help.
