Brake light stay on

Brett,

Likely it is a brake light that is on. Brake lights can actuate with the ignition off, usually by pressing the brake pedal. Test the lights, brake and turn signal circuits, but my bet is a brake light switch out of adjustment.

The brake lights work regardless of the ignition switch. There is normally a switch mounted under the dashboard, that presses against the brake pedal hangar. Normally, when you press the brake pedal, this switch loses contact with the hangar, and the brake lights come on. If the switch gets broken or out of adjustment, the brake lights can stay on at all times. This will eventually kill the battery. Readjust or replace the brake light switch.

Brakes lights work regardless of ignition position. Check the brake light switch (behind brake pedal). Could be stuck in on position.

Sounds like the brake lights are staying on, which is probably a faulty brake light switch on the pedal.

If the lights only stay on when key is in ignition, your central brake lights (or one of the lights) are out. The other lights stay on as a warning that the centrals(or other brake light/s) are needing replaced.

Try pulling back on the brake pedal if lights go off then either switch adjustment or the brake booster is allowing the pedal to drop down if it's running (vacuum) or brake pedal mechanism is binding.

bad earth to lamp clusters usually when tow bar electrics fitted - or chaffed wired in lamp feed

hiya if the rear lights are remaining on ? with no ignition it will be the brake lights staying on this is easily remendied/ checked by trypulling the brake pedal up by hand and see if lights go off ? if so then you will need to adjust the b/light switch which is positioned adjacent to pedal and can be screwed inwards towards the pedal untill the plunger on switch is pushed into the switch which puts lights off ensure pedal is fully up then adjust switch reconnect the wire/plug and press pedal slightly to ensure b/lights operate ok and then go off with pedal released ? on hyundai the brakelights do not req ignition on to operate hence more likely problem is as above good luck

Is it your tail lights or Brake lights? My 88 Couger had a brake switch that went bad and the Brake Lights stayed on.
