the only other suggestion I can add, is buy a couple of used MKIII headlights (relatively cheap), and practice, & experiment on them.

I find for myself (as well as probably for most people), that if I'm working on a pair of some thing, or 3 or 4 for that matter, the first one will always come out horrible, and by the 2nd into the third one, everything becomes butter.

I feel for you, but in fairness at least you put your balls on the line and tried it. There must be a way of doing it, but how many lights would need to be broken to find out

What about trying a heat gun directly on the seem? Might loosen the seal and, if careful, not melt the plastic housing.

In all honesty that would probably take DAYS to do, lol. The guy that helped me has baked a lot of headlights, and even he was frustrated.

Oh well, this opens up the door for me to install what I REALLY want.

If any of you have thought about trying this out, don't do it. You'll just get frustrated. These things were not meant to be taken apart, that's for sure.


Exact same thing happened to me. Ive been told I should try putting them in the oven at 200 degrees to soften the glue, but havent got around to that yet...

200 isn't going to work. That's how I melted a corner of a headlight. The glue will not give way no matter how long you leave it in there. Trust me, I left it in TOO long and it still wasn't budging. The back part of the headlight was getting soft but the glue was like cement. No dice, sorry...

hmm, what about a chemical that will dissolve the glue but not the plastic? ...well, at least dissolve the glue faster than the plastic. Acetone perhaps? I am not a chemistry expert by any means... I'd try acetone, test it on a not-so-noticeable part of the head light to see if it dissolves the plastic; if it does not try it on the glue.

Re-read what you posted and ask yourself -- is it worth trying to take apart $900+ headlights only to burn off your fingers or put holes in the plastic (or vice versa)??
