The brake lights or parking lights stay on while the car is in drive and will not go off.
How do I get the brake lights to turn off while the car is in drive? on 2000 Mercedes-Benz E320
Sounds like you need a brake light switch.
try lifting up on your brake pedal and see if that works. if so repl or adj your brake light switch, i believe this one is not adjustable externally so that why it may need replacing
