Ok, just did mine this morning, with a little help. Heres some tips for the un-initiated.
Follow the manual..... its a little fiddly, with the low beam being trickier of the two. Just keep hold of all the clasps which might fall off. You will need these later!
I had problems getting the bulb stem out of the plastic holder... just wiggle and pull lightly - it eventually comes free.
As per manual. However theres bugger all room between the black fuse box
to wiggle the cover free. Remove the headlight panel. Its not as scary as it sounds. Simply undo the 3 (maybe 4?) bolts on the top of the light fitting. Wiggle the light panel (the whole lot which is the front of the car light) out a few cm's. You don't need to pull it all the way out.
This will give you a couple more cm's to get the bulb covers off at the back.
Screw everything back together.... if you're left with any bolts/screws/clasps... pray.
Place the new bulb in the socket first. Put the metal clasp into place to hold the bulb. Connect the electric socket to the bulb at the end.
This might sound stupid, but when I took my old bulbs out
the clasps were over the bulb AND the wires/socket- which made it really fiddly. I didn't know any better - so tried to reconnect it in this way. Which is almost impossible.
Keep the plastic socket & wires til last.
Took me about 5 minutes. Of which 3 was spent wondering whether I was about to kill my car.
