65 Dart. Brake lights and dome light stay ON....Why ??

I am just getting this old neglected beater running.
1965 Dart, originally a slanty but when I got it in 2015, it had a 318, a slip yoke 904 and a few hokey "changes". I have erased some of the crimes and got the thing up and running. The dome light and brake lights seem to stay on all the time though. The brake light switch is in place and the slide does move. The horn wanted to stay on so I pulled the wires from the horns until I can diagnose that.
This is odd...Most cars I buy to fix up have no horn, no dome light, no taillights either!
What may be causing this? I am still learning how to work on electrical stuff so any help is appreciated!
