Tail light lens repair

Just got an localized impact hit on my tail light lens this morning, backing into a vise in my garage. Its a second generation tail light and the impact is right over the main bulb.
The impact caused spider like crazing about 2 inches in diameter, and did not break through. I would anticipate that moisture could get in the cracks and condensation could easily occur.
Anyone have any ideas on repair. If this makes any difference, I do live in a cold climate where it snows, and the temperatures are usually in the teens during the day in the winter.

 

i've got the same thing from a baseball bat(oops)over a year ago along with a bb gun shot in the side of it(wont go there)and i have had "0"issues with any moisture or iceing.good luck

 

Thank you.

 

I just busted my '18 Tacoma tail light, but I have all the pieces.
Easy fix with glue, but......
What kind of glue?
