How do you seal a cracked tail light?

One of my tail lights is cracked and it keeps filling up with water. Replacing the whole enclosure costs about a hundred bucks, and I can't seem to find the plastic lens portion for sale by itself.

Would simple super glue work? What's a good, clear substance I can use to seal the cracks, but not block any light? Nail polish?

    I'm experienced at fixing this problem cheaply.

    You have two tasks:

    1) dry out the interior of the light completely
    2) once it's completely dried, seal it

    As previously suggested, drilling a hole at the bottom of the light to let moisture drain is suggested. If you can remove the assembly completely and bring it into a warm dry house, that's suggested.

    Using a blow drier, you can warm and dry the air around the hole you drilled, which will slowly warm and dry the air inside.

    Once it's clear and dry outside, lightly sand the area over the crack, as well as the area around where you drilled the hole. This will roughen the area around where the moisture is getting in enough to let glue stick.

    Use clear silicone adhesive. Put a small bead along the crack, and a little glob over the hole. Smear it flat with your finger, but make sure everything remains covered.

    Let it dry, reinstall, and BAM!

    You can buy clear red tape at the auto parts store made specifically for patching broken tail lights. Whatever you do, make sure it's transparent red. You can get a ticked for having any white light showing through.

    You could try just drilling a hole towards the bottom of the taillight so that the water drained out instead of accumulating.

    You should try using a combination of organic honey and Juicy Fruit chewing gum. If this does not work, try paying a $100 for the whole enclosure and move on.

    I'd think glue gun glue would do the trick. Unless the hole is fairly small I think they'd want something more flexible than super glue.

    I believe you can drill a small hole, and use the filter part of a cigarette to filter out the moisture by fitting it in the hole, but that would be a very d.i.y. kind of way to go about it. if you can afford it i'd say get it done professionally.
