When I turn my headlights on my brake lights come on. When headlights are off brake lights work like normal.
If you are sure they are your brake lights and not tail lights then I would check for shorted bulbs, filaments broke free and shorted to the other filament, bad sockets, damaged or shorted wiring in the rear lighting and don't forget to make sure the grounds are good. It seems like Asian vehicles wen they get a little age on them the grounds start to go away.
Had a loose wire to one bulb. Blew out the light sockets with air and replaced all bulbs. Crisis averted. Thanks
When i turn my headlights on and push on my brakes.the back brake lights go off on the driver side of my 92 toyota corolla what keeps making it do that
Grounds are a problem with everyone’s vehicles when it comes to lighting, bad sockets is another, also cross circuit inside lamps.
