shift position sensor failed, or wires are shorted
yes
The brake lights should not come one until you step on the brakes. The tail lights should come on when the headlights are on. If they're weak, maybe there's dirt in/on the lenses or maybe the bulb is old and clouded. Change the bulbs and see if that improves things.
Check stop light fuse Check bulbs (double filamented smaller filament is for stop lights larger for taillights) Check alignment and operation of stop light switch
It would either be a bad wire in the circuit from the brake light switch on the brake pedal to the bulbs, OR the bulbs have 2 filaments in them and the one that comes on when you apply the brakes are worn out, OR someone put the wrong bulbs in(single filament). I would change the 2 bulbs first.
Break lights come on when you step on the break, they do not come on when the head lights are turned on.
May be its time to change your brake pads and rotors.
If you step on the brake pedal , yes
you may have your brake light socket and your back up light socket in the wrong holes. Or you have a short but that would probably leave you with a blown fuse and no lights.
Brake and parking lights? Are you sure, the two aren't interconnected. Maybe it's just the brake light. If so, sounds like a bad brake light switch. If you step on the brakes and the brake and parking (sometimes called running lights) lights come on it sounds like you have a real problem. Suggest you have it checked right away.
Light on dash? Check fluid level in master cylinder
You step on the brakes.
brakes, or no sun
