Chris, Thanks so much for your reply to my question. Since I posted it, I found out a few things from a local Volvo mechanic. Like you, he said that the fog lights are bright enough to make people behind you think you are using your brake lights, so you're not to use them often. Apparently for that ...

Just got a 1993 240. Everyone tells me I have a tail light out on the passenger side, but looking in the owners manual, it shows that only the drivers side has an illuminated fog light. Is that true?
