Warped rear lights

[moar_swimps]

I got my lights (front and rear) tinted about 3 months ago and this past month I've noticed they've warped at the top... I have no idea how this happened and I was wondering if anyone can give me a clue as to what happened
Here's how the lights looked about a month ago...

New rear lights are reasonably cheap, I just don't want this to happen again.
Thanks

Huh, that is pretty odd actually...

I could be dead wrong, as I don't and have nor have I ever had tinted tails or anything for that matter, but maybe the tint keep in excess heat causing the plastic to get too warm and warp??

I have no evidence to back that up, but it would be the first thing I would think of.

^ my only thought would be that too, maybe the tint helps it get hotter and holds the heat longer...next time its a hot sunny day you should put your hands on the lights to see if they do get hotter than normal.

Wow that looks crazy.

Wow, that is crazy! Did you spray tint the tailights? I've used the spray tint on all my cars that I have had and I have never seen that happen.

Yeah, it's spray tinted with a clear coat on top... I'm thinking of getting another set of lights cuz they're pretty cheap and put a lighter tint on them.

The lights are hotter than normal, there's a definite difference from the top of the light to the bottom of the light.

Thanks everyone!
