I was changing the low beam headlight on the driver side which is a bit awkward to get to. It probably would have been easier if I had completely removed the filter housing but I didn't. Anyway, got the old bulb out, put a new bulb in and just loosely put it through the hole. I switched the lights on at this point to test that everything was working and it was fine. Now I should have put the lights off but I didn't, instead I went in to rotate the bulb to lock it in place. It fell out slightly, the glass of the bulb shattered and there was a bit of a bang. I put another bulb in and tested it but it didn't work. I tested with a second bulb and it didn't work. Turns out there is no voltage at the connector, I assume there was a short when the bulb smashed and it has blown a fuse.

My Lexus is a IS220D 57 plate and has the type A engine compartment fuse box. According to this the left and right headlights are on the same 30A fuse, but my passenger side light is working fine. Is there another fuse somewhere that just controls the driver side? I wouldn't have thought there would be two fuses in line. Any other ideas?

Any help much appreciated as I can't seem to find anything online.
