Parking lights may stay on after a BMW is turned off because the headlight is bad. A faulty relay could also cause this problem.
Most likely, the switch that controls your parking light is stuck.
because the lights are not controlled by the ignition switch; they are controlled by a separate light switch.
There is a second light switch that activates the parking lights without the key being on. It is on top of the steering column behind the steering wheel. If this switch is turned off and the lights remain on when the key is off, there is a malfunction in this circuit.
Bad switch. Easy fix- cheap part!
Usually because the switch that controls the light is stuck in the 'on'position. easily replaced w/ aftermarket switch from your local NAPA store.
Check the brake light switch located under the 1989 Toyota Corolla. If the switch is stuck the parking light will continue to stay on.
The switch probably turns the light out when the switch makes connection, then the light is on when there is no connection (like when the wire is not connected.) Reconnect the wire and push the switch to see if the light goes out. The switch is most likely out of adjustment or bad.
The parking brake light stay lit on the 1999 Mitsubishi Montero sport the parking brake is working and you have not put the light off.
Check you brake fluid and the brake switch on the proportioning value. If the fluid level is ok then disconnect the switch to see if the light goes out. Also check the parking brake switch.
Defective switch?
Rocker switch on top of the steering column.
It might be the brake lights. If it is, check the brake light switch connected to the brake pedal. It's right above the pedal and if it's slipped or adjusted wrong the light could stay on all the time. A brake light switch that is stuck like that can also prevent cruise control from working. On the other hand, if it's the WHITE light, it's probably the backup light switch that's stuck or adjusted bad. If it really is the parking lights, the fronts should be on as well.
