yea on that part there's different ways to do it. the easiest way is to push it down on the arm using a long flat screw driver (not that hard, just as far as it will go) and then pull up the on the reflector and it will pop right out. i haven't broken any of the white connectors really doing it that way. I've only broken one but that's when i was doing the opposite with trying to pry it up instead.
i already asked if i could add/change my original post, but tim (admin) told me since it was so long ago that i posted he cannot. i was thinking, if i ever come across another headlight that needed to be open, i'll make a vid and post it here.
