Hi
I removed the nearside headlight bulb on my 2001 Stepwgn when I was putting together a set of spares to take abroad.
The bulb on mine is a bog-standard H4 60/55w halogen which you can get from Halfords or anywhere (eg.
http://www.phoenixautobulbs.co.uk/osram ... p-611.html). I already had one from a previous car so didn't need to buy one.
If it's the nearside, it's simply a case of removing the coupler, rubber cover, catch and then the bulb.
If it's the offside, you have to push the reservoir tank to one side and remove it first (so the manual says).
Regards
Brian
