My right front amber reflector lens fell off its black plastic backing.
I tried double sided outdoor mounting tape that does a great job on some things but I couldn't trim it well enough to get contact on the various surfaces behind the lens.
It may have fallen off by itself since I couldn't see any adhesive on it and it didn't snap in.
It's more likely the sides of my trailer bumped it and knocked it off while loading or unloading (yep it's that tight).
In any case I'd like it to look as good as new since the pieces aren't scratched or broken.
I might try black silicone RTV if I have any.
I have crazy glue somewhere.
I have duco cement (plastic model glue).
Elmer's and gorilla glue are available.
I'd appreciate hearing what works before experimenting.
Thanks In Advance,
