Have done exactly that! I removed the bumper as it was easier to get to one of the screws.... You do have to remove the arch liners too! 6 poppers off the top, 5 or 6 screws under the bumper then 3 screws under the arch on each side, they are where the bumper joins the fender...
Remove headlamp, think its 3 screws, wobble headlamp until the offending bulb drops out then put it all back together!!
re the silver bits, what side is it? PaulT, I could reroute the light we talked about to IanS if its the same side...And ask him to make th same arrangement....
