I’ve never seen the lights like this glued in. The lights have studs in the back, they go through a hole and you put a nut on them.

Those lights are bolted in, there’s no adhesive. There’s probably a seal but that’s to keep water from getting into the tailgate.

It’s not on them. They don’t pay to fix your wreck, it’s the other way around. It’s part of the wreck that wasn’t noticed when it was being fixed. It happens, and it can’t be helped unless they park it outside and let it rain and then check it and nobody does that.

If insurance paid for the wreck, get with the insurance company to pay for a new one. If you paid for the wreck, you could have paid for it when it was fixed but it wasn’t noticed so you pay for it now.
