Brake lights stuck on every now and then and front lights

Check the brake light accuator switch it is up above the brake pedal and its probably just unhooked from the bracket all you have to do is put it back in the bracket and lock it in

The brake light on the dash or the brake lights on the rear of the car?

If dash then check the brake fluid. Could be when you move forward it moves the fluid enough to make the light come on. So check and top off the fluid. If really low check your front pads.

if rear lights look at the brake peddle to make sure it is firm and not rudding on teh brake light switch.
