Okay, i had a problem last week when a dipped beam light went off.. i left it for a couple of days and then classically my other one went last night so I replaced one today, went to test it and it still doesnt work!

Any ideas? Is it possibly a fuse? I dont think it is a fuse as they went at different times. I would have thought if it was a fuse, then they would have both died at the same time?

Any ideas?
