I was a lot tougher than I thought it would be to get into the headlight. I did crack the very edge of black peice in one spot. The glue did soften, but not a whole lot. I found that I needed to turn the heat up on the oven, and that seemed to help a little bit. I forgot that the heat needed to be higher because of my altitude. I did remove the piece from the lens of the headlight, but when I tinkered with the side marker it seemed to be on the chrome piece quite well. I did see the tab you are talking about. So I just need to remove that tab and then break the glue? Seems easy enough. Did you do anything to remove the leftover amber lens where the glue is. I was thinking that a sanding bit, and a lot of care, might be enough to remove all traces of the amber. By the way what did you use to seal the headlight back up. I figured silicone caulk would work. Have you had any condensation issues since?
