Are you the original owner? Are the taillights and the wiring 100% stock? (Stock = No sequentials, all 6 lights shine for taillights, but only the outboard 4 light up for turn signals.)

Well, typically those issues are ground issues, or possibly since you mentioned the rain a Smart Junction Box issue? Feel the carpet around your passenger side footwell under the dash and make sure it's completely dry. If it isn't, the the SJB is likely your problem from what I understand. If it's dry, pull the bulbs and determine if it's the brake light filament or the tail light filament that's illuminated when it shouldn't be. I'd also check all of the wiring and connections for your taillights behind your trunk carpeting and make sure everything's completely dry. Unplug the harnesses and make sure the plugs are all completely dry and there's no corrosion anywhere. That's where I'd start. Electrical Gremlins can be a real PITA.

Well I removed both brake bulbs out and let it sit over night since it was raining hard all day and I thought maybe something got wet, next morning I went back and put them on and it was ok they weren't on when the car was off, so I tried and turn on the car on and the battery was dead, I jumped it and everything was fine but after an hour or so of the car being off I had to jump it again and came to a conclusion that I need a new battery since the sticker on the battery says oct07!. Is the dead battery what caused my problem or do you think the rain did? I believe and hoping it's the dead battery.

did you feel for wet carpet on the passenger footwell like John mentioned?
I'd also bet thats it.
if its damp, pop the plastic panel off let it dry out...the cause is usually the drains under the cabin air filter- leaves and stuff clog the drains, then one hard rain it will back up and leak into the car- almost every time ive read abut it, one of the brakelights or turnsignals quits or wont shut off was the symptom that eventually was found to be caused by a leak... I havent read of any permanent damage from the 'Smart Junction Box' getting wet, but it sure cant be good for it...wont cost you anything to pop the cabin filter and look way down under for debris in the drain- theres 2 drains, one on either side of the tranny tunnel, I couldnt see the drivers side at all but felt back under it seemed fine- but the passenger side of mine was nearly solid, filter was nasty- some black mold(!) definitely should be changed/drains cleaned more often than every 4 years

Well new update I double checked the passenger side and the carpet was damp all the way back to the back seat where the feet go which was even more wet! I had to open up the carpet by slicing open a part to remove the water from under the carpet
, funny thing is I checked the cabin air filter and it was dry no mold or anything. I wonder if I went through a deep puddle and the water came in through the passenger side. 
well I cleaned it up and hopefully it won't happen again.
