I managed to change sidelight bulb, not an easy task, you have to remove headlight completely (quite easy), undo the screw near the wing edge, then there's is a small metal flat strap on the grill side of the light that you pull upwards which will release the light, then graduly lift out the light, then you have to remove the lense from its backing, then pull the little sidelight bulb from it's holder, on refitting make sure you completely seal the lense to it's backing or it will let the damp in, very tedious but if someone offers to do it Let Them.
Took about 2 Hours
