brake light switch, & won't turn over.

1, battery is fully charged, 2, it would not even turn over with a jump, I have full instrument lights, and it won't turn over. Bulbs are good, last few nights, when car isturned off, brake lights stayed on during the night. Even when went to park some where, they stayed on. If I touched the pedal, sometimes they would go off, then come back on.

get a new battery... i had the same problem and at the dealer they replaced the battery
