update on headlights

Ok, i followed all the instructions i was given except one. I pulled off the bumper and removed the headlight that was fogged up. Everything looked good, i had the headlight out for half of the day and i put everything back together last night. I get up this morning and see that the same headlight is fogged up just a little. I think it will get worse. I forgot to "seal it up". I wasn't given clear instructions on what to seal and how to seal it. I'm assuming its the rubber seal that goes around the bulb that i have to seal right? what if there is a crack somewhere else in the headlight that i can't see?

Check out this link and follow the directions for resealing unless you want to do the whole thing.

it is the actuall 2 pieces of the headlight assembly the clear plastic that you need to reseal.
