Default Re: Brake Light Problem..

Every time I pushed in the brakes the light malifunction light would display on my dash then go off when the brakes were not pressed in. Checking the lights again everything seemed normal. On my way back home the same night I got pulled over by a cop because all of my brake lights the left and right and the bar would remain on no matter if I were pressing the brake nor not. Last night the light indicator on the dash was constantly on when I turned the car on and all three of the brake lights were on and would not turn off no matter what. So I played around with the back left brake light and tried to replace the bulb just to see if it would change anything and now the back left brake light will flicker on and off with no rhyme or reason and it seems that when the brake light it on all three of the breaks lights will come on and when the rear left brake light is not on the other two lights will work normally. I can't find anything on this forum but it kind of seems like the wires for the rear left brake light are malfunctioning or maybe it is a fuse or something? Anyone have a problem like this before?
What happens when you leave out the replacement bulb?
Where the other lights on when all the brake lights were on as you said it was night?
There was a problem like this some time ago and the problem was the bulb was in wrong or it was the wrong bulb and the brake filament was getting power from the night light circuit, somehow the power got across the bulb contacts and once that bulb got power the other brake lights got power as well.
The wrong bulb had the two terminals on it differently spaced compared to the correct bulb. The bulb may have been mislabeled.
