Not sure if its the bulbs or something else. Both the foglights have darkened objects in the center, leading me to think the bulbs are blown. There does not appear to be any fluid in them. And yes, I've checked all the fuses in the fuse box.

 

Are these sealed bulbs or inserts like the headlights? How are they removed/replaced? Last time, the dealer charged me something like 180 dollars to fix one (it was definitely leaking, had fluid init, etc), and I'll drive without them before I do that again.

You stated that the bulbs are dark and that would mean they are probably blown out. I would guess that they are replaced by pushing in on the bulb and turning it but I really don't know for sure. If the base is round then that is what I would try to do. If the base is flat they may just slip out.

Which car do you have and which foglights? Replacing the bulbs is different for the two versions of foglights on the early models of Impreza. If they are stock and not aftermarket foglights, you have to remove them from the bumper bracket to be able to get to the back of the housing, remove the back cover, and then get to the bulbs for replacement.
