The side light/dipped beam lamp on my MY02 Prodrive headlight conversion is damaged... dealer is being a bit difficult so where do I get one independantly and is it simple to fit

 

I dont know where to get them but as they are Hella lamps, it may be worth trying Hella direct.
Fitting them is easy, but take care when removing the lamp caseing from the 3 ball/socket type joints, as you can easily damage the lamp unit, I used a pair of long nose plyers and plenty of WD40. when fitted, roughly guess the height position by matching the light on a wall 3 feet away with the other side (or pop down to your local garage and donate a fiver.
