Two filaments in the light bulb. One is the tail light, the other is the brake light.
You need to change the bulb. The filiment for the brake light part of the bulb is "open" or burned out. The filiment for the tail light portion will still work.
Bad earth connection at light cluster?
Probably a bad bulb They are double filamented with the smaller filament for stop and turn Larger is for tail light
According to my Haynes manual, Black on both sides is ground On the right (passenger) side, Dark Green is the brake light/turn signal and Brown is the tail light. On the left side, Yellow is the brake light/turn signal and Brown is the tail light The center brake light should have a White wire (12v+) and a black ground. FriPilot
check the bulb, it has two filaments, one for tail light, another for brake light and indicator. if the turn signal works, it's not the bulb, but a power supply problem.
The ground for the brake lamp. When the tail lights are off, the tail light circuit can act as a ground for the brake light. When the tail lights are on, it can't.
No, it is a brake light.
tail light bulbs has two filaments inside. One for regular lights and a second for brake lights. One filament is burnt out. Change the bulb.
Many taillight assemblies are equipped with bulbs with dual filaments, one for tail lights and one for brake lights. If you have one bulb with two filaments, then the problem you describe sounds like the brake light filament in the left bulb is burned out but the tail light filament is working.
If you mean the brake light switch (tail brake light) , is in the upper part of the brake pedal. Just follow the brake pedal up and you will see two rubber buttons(switch stopper) and their respective switches, those are for the brake light switch(left) and the cruise control(right)
bulb is out The bulb has two elements in it, one for the tail light and one for the brake. The brake one is also for the directional signals.
