Brake dash light & turn signals

[DGraber460 at aol.com]

On my URQ, I have puzzling set of circumstances.
My dash brake light started flickering about month ago and gradually came to 
the point it is on constantly (brakes are fine & bomb 4 months old). This 
week my right turn signal started flashing rapidly. I surmised I had a burned 
out bulb.
After checking all the bulbs front & rear last night (Replaced 2 that 
appeared OK for good measure), this AM the brake light flickered, glowed, and 
went out periodically. The turn signal still blinks rapidly _sometimes_, not 
always. Are these related, and what are the "usual suspects?"
TIA
