| JPM, you are correct in saying the headlamp is in two halves.
You need to find the bolts, and I think theres around 9 or so, that bolt it together.
Some of the bolts just hold items inside like the projector lens, fuse etc.... these are the ones to be careful with as your working at a funny height and it has a habit of falling apart in your hands! cover up your front mudguard!!
You will probably need to take all of them out anyway, as the Pierbon bracket mounts the relays and fuses.
And..I did a little drawing, so when you come top put it back together in 5 yrs.............................. |
