If you set the oven to 300 degrees and leave in there 15 -20 min at a time it softens the glue. You have to be careful because the plastic feet from the headlight will start to melt if you leave it in too long. I tinted the headlights first, but the look was not good enough for me. The tint cuts your visibility. The turn signal still looks normal. Headlight actually performs better. More of a focused beam.
