My taillights were cracking around each screw hole. Fractured from stress, maybe flexing of the body, not sure, but both taillights looked like crap around the holes.
I went to my hobby shop, and bought some THIN CA glue.
Any hobby shop will know what you're asking for, you want THIN CA.
I carefully applied it to the backside of the fractures, and watched my cracked taillights go back to looking like brang new!
The thin CA is VERY thin, and wicks it's way into the fractures, and even if it doesn't look like they're fixable, this is worth a try.
The only spots I couldn't make look like new were where some of the colored plastic had actually broken off.
I'm going to find some red "something" (the red gel part of "prell" toothpaste comes to mind lol) to fill those spots (maybe a piece of red Gummy Bear!), but I cannot relay to you how good this works to fix your cracked taillights.
Just wick it in from the backside, carefully, and watch the cracks go away!
Be careful, the thin CA is THIN, work slowly, add just enough to cause the fractures to disappear. IT WORKS!
I'd post "after" pics, but they just look like new lenses.
