Possible EVIL MFG 3rd brake light issue

I know there may not be many people with this light so responses may be limited.
But I installed this light about 3 months ago. Since then I’ve had two dents show up on each side of the light. I did do some moving with big furniture not long after install So thought that may be what caused the dents but I didn’t think I was even close to that area.
Had a dent guy remove the dents. A month goes by since that and this morning I’ve noticed the dent is back on one the passenger side.
Could this be a possible issue with the light being mounted up there. Is it somehow tweaking the cab. Strange to me how they are just showing up. 95% of driving lately has been on the highway so I wouldn’t think the cab would be flexing this much to cause issue.
I’ve tried taking pics but with the black truck you can’t see them.

 

Nope. Don't see how it would cause an issue. I've had the SS Built 3rd brake light, which uses the same steel housing, installed since May of last year. I've had no issues.

 

I have had the EVIL 3rd Brake Light installed for a few years now and no issue ever with any dents... but you did make me go out and look

 

Nope no issues here. No reason it should cause that.

 

Yea it’s pretty strange. I didn’t think it would cause a problem but i don’t know any other reason they would show up.
