Check the fuses.
Check fuses for brake lights. If your brake lights aren't workings the truck will not release the parking pin as it needs the signal from the brake switch on the pedal.
If you pull the parking brake up the running lights will go off - if not - start the car with the parking brake on and that should work, if you want to drive with the running lights off - you can get away with "slightly" putting the parking brake on (just so the parking brake light goes on in the dash but the brakes itself makes no contact) Otherwise you can remove the relay that controls the daytimes - maybe even a fuse
Check fuse for parking lights Check headlight switch if replacement required also replace harness--they heat up and don't make good connection on new switch
What fuse is for the 2005 Ford mustang Rear Brake lights?
How the brake lights work on a 66 Mustang is very simple. Power goes from the headlight switch to the brake light switch, then through the turn signal switch and back to the brake lights. There is no fuse in that system. There is a self resetting circuit breaker in the headlight switch, but, if that was tripped, none of the lights on the car would work. The first thing to check is the brake light switch itself by bypassing it. Unplug the connector from the switch and run a jumper from from one slot in the connector to the other. If the brake lights come on, replace the brake light switch. If they don't, the problem is either a wire has lost continuity or there is a problem in the turn signal switch.
The most common cause for brake lights to be out on a 2001 Mustang GT is a blown bulb. There are some instances where there is faulty wiring.
If your parking lights are on and your left brake light doesn't work, the brake may have burnt out. You might also have a wiring problem.

No , the rear brake lights do not turn on when you use your parking brake , just the brake light on your dash is supposed to come on
the turn signal switch is probably bad
on the back of the car
Fuse for parking lights probably blown.
