undo all 3 11mm bolts on headlight case. .
Unplug the 2 plugs on back of headlight. . ull feel a button "clip" that when pushed lets u disconnect the cables. . u can do this after wrigling out the headlight abit. . .
Once the unit is out unscrew that big cap. .
unclip headlight socket and take out headlight and DO NOT TOUCH!! unleas its broken and u dont want to keep it. .
Insert new headlight into the socket and clip back in (make sure its clean though!!)
Wriggle headlight unit back in place PATIENTLY. . no easy way of explaining of how to get the b***h back on really easily
