Headlight Sealant/Adhesive

[Blackrosepet]

First off, I have aftermarket Cobra headlights. Walking out to the car today, I noticed that my headlight lens was just basically hanging there. I could take a hold of it and pull it from the housing. What should I use to cement these two pieces back together? Will silicone adhere them as well as seal?

I would probably use windshield adhesive (if you can get it clear). That's tough stuff. A clear silicone might also do the job, but won't be nearly as strong. Don't use epoxy.

If you cant find clear window adhesive, use some clear silicone. If you CAN fins clear window glue, add a bead of clear silicone after you glue it to prevent leaks.

Why not epoxy? I had the same problem with my headlights, and some epoxy did the job really well.

Yeah, Sikaflex is what you want to use. Flexible and extremely good adhesion. Comes in 5 colors i beleive, and be careful when applying, b/c it's a PITA to get off if you make a mess.

I'm not 100% sure why. I recall using 5-minute epoxy on plastic before and it had melted part of the plastic away. I could be mistaking it for something else though, memory's not as sharp as it once was.... or wait now... it never really was that sharp to start with
It may be a better idea to use a flexible adhesive to do this, and epoxy tends to harden like a rock, and become ugly and yellow with time. Its good for a quick fix though.
