I was changing out a dead fog lamp bulb on my 95 3800 camaro this afternoon because it turns out that driving through 10 inches of standing rainwater will introduce a bit of 'dampness' to the bulb. Anyway, I was resealing the lens onto the housing with a bit of silicon, and to check the seal, I blew into the socket hole to make sure there was no air escaping. I found something peculiar....

The first picture shows a circular blue sticker over a 3mm hole. The second picture shows the hole with the sticker removed. My best guess is that the hole is there to maintain a pressure balance with the outside world, but it sure looks likes like a gaping big hole where moisture could enter if the sticker ever falls off. Plus, you'd only need a pinhole for pressure balancing.
I'm plugging the hole with silicon before I reinstall the lamp. Anyone think this is a dumb idea? Or better yet, do you have an answer/guess at what my mystery hole is for?
Uhhh... er... that last sentence didn't sound so good.
