55 f100 brake light stays on

My 55 f-100 brake lights were independently staying on. Anyone with thoughts as to what the problem may be will be appreciated?

Typical bad pressure switch. They go bad one of two ways. Too much pressure required to turn on or they stay on.
Edit: And, oh yes, welcome to the forum.

Ditto on the switch and ditto on the welcome. You can use a test light to see if there is voltage on both sides of the switch. (There shouldn't with brakes off)
