Intermittent 3rd brake light problem...

I just remembered... Before putting my car away for storage I realized my 3rd brake light stays on sometimes when I park my car in my garage??? LOL it turns off by itself if I just pound the rear spoiler a few times with my fist

Any ideas on where to look or what to do? I think this problem may have been draining my battery a bit last year I've got a new Delco battery going in next year and don't want this killing it all the time.

Thanks.

Today I got around to checking this out...

I removed the rear light in the spoiler, one light bulb had blown and the other one was the bulb that would keep staying on even after I shut the car off.

I replaced both of them, and now they both stay on even after I shut the car off anyways to avoid killing my battery I just removed both lightbulbs for the time being until I get this figured out. Any ideas where I could look? maybe it's a simple fix?? I'm not that good with electrical systems so any help would be great..

Also I checked to make sure nothing else was drawing current on my battery, and with the bulbs removed, I got a reading of 0.01 on my ammeter (it would show 0.07-0.08 on intial contact of the leads, but then would settle down to 0.01 or 0.00) I guess this is normal right?

Yeah so it ended up being the brake light switch, when I would activate the brakes and the brake pedal would come back to it's place it wouldn't make contact with the switch all the time. What I don't understand though is why this only affects the third barke light and not all of them?
