As said, on many modern vehicles, it is almost impossible to get at the bulb. On my truck it involves undoing 2 torx screws, which means you can pull the plastic headlight surround off exposing 4 more torx head bolts, which then let you swing the whole light assembly out so you can change the bulb...then put it all back together. We have found it much easier to tilt the cab up about 12" and just reach in and change the bulb in less than 2 minutes!
BTW, has anyone noticed how many cars have both brake lights 'blown', but the high one in the window still working? That really annoys me too!
