Brake lights issue help!

[Donfico]

Hello 318ti family, I just had a lil problem with rear brake lights, when I turn the headlights on then the rear brake lights stays on. When I turn the headlights off, rear brake works well but the corner lights will lights up at the same time when the rear brake lights lights up when I hit the brakes... The police pulled me over and gave me warning. I gotta fix that asap -___-

short in the light circuit probably

Sounds like resistance to ground. Check the ground point in the rear.

make sure you have all the correct bulbs, a parts store should be able to tell you what you should have

[Bobtail_Bimmer]

Did this just start happening or gradual? Did you do anything first like new bulbs, wireing work, tail light swap? This will help narrow down the problem.

I stripped the interior down, currently in work to find out. -___-

Do the brake lights use dual filament bulbs? sounds like someone installed standard bulbs.

I've had a dual filament burn out twice and the bub internally shorted....New bulb fixed the problem.

i had the wrong bulb in once...everything went whacky.
i replaced it with the correct double filament bulb and all was well.

I found the problem, it was bad brake switch. I replace all the brake blubs new. Now its all working fine. Whew
