The project was going so well..... And I was so close to finishing..... While resealing the light I learned why not to have the heat gun pointed straight at the headlight.
All the lights still work. There's a hole about the size of a quarter in the plastic casing of the light. I'm going to attempt to seal the hole, though the odds I make it 100% water tight are low..... Either way there's probably a new drivers side headlight somewhere in my future.
Edit: It's been some time and the light seems to be waterproof after my repair!
