That reminds me of when I once changed a headlamp bulb on a Ford Focus. When I'd finished it looked like a hand grenade had blown up in my hands. Needless to say, the next time it needed doing it went to the garage where the mechanics are equipped with boneless double jointed hands.
On Focuses (focii perhaps?) open the bonnet and there's a big screw on the slam panel (it's the one attached to the headlight, there's a clue there somewhere), undo the screw, headlight comes out, they designed it so you can change the bulbs without chewing your hands up, funny old game innit
A few years back I had to pop down to the local Vauxhall stealers dealers for some parts, and while waiting at the parts counter I amused myself watching one of their chimps changing a foglight builb on a Zafira B, the official procedure is to jack the car up, remove both front wheels, remove arch liners, then remove the bumper to gain access to the rear of the fog lights, the reality is you stick the car up on the ramp until it hits the stops (unless you're short), hang off of the under tray and stuff your free hand between it and the bumper, where you can just grab the bulb holder and do the job*, saves you an hour and a bit in labour though (but doesn't work to replace a complete fog light unit).
*Get an adult to help you with the cutting out...
