Can the bulb in my rear foglight be changed with a brighter one? Just wondering.

I'm sure you can do whatever you want in there! Right now I'm set if someone cuts me off, but it would be fun to have something in the back to ward off eager soccer moms in suburbans and X5's and rx300's and whatever else rich poeple waste their money on that blinds me at night (and in silicon valley, there are all too many of them . . .)

disclaimer: I follow all of my state's vehicle laws . . .

You could activate the other rear fog lite and put in Hella Halogen bulbs. I've done this with a cut off switch and it works just fine. The halogen bulbs scare the bumper kissers away. Or you could put high capacity marker bulbs in both foglites and go with that.
