This light means over drive. Look for a switch that has overdrive on it or when you put it in gear you are putting the transmission in D with the letter O around it.

Break light stays on and I have to pull up on the break to make it go off on 1998 Mercury Mystique

Might be the master cylinder.
The light usually means the system is low on fluid or the equalizer valve is stuck.

My break light is not tuning off(i dont mean light on dash board).the light at the rear of the car(mercury mystique 1998)

It could be the switch on your brake pedal or it could be a short in the brake wiring harness causing the brake light to stay on.I,m not sure but I would also check to see if those cars have a relay in the brake circuit.

good luck
