Reply To: Brake lights not working

Ben,

If neither stoplight is working that suggests the fault is probably before the lamps.

I suggest you start by confirming you have power to the switch. If not, you will need to trace the power source back to the battery but remember the brake lights should be fed via the ignition switch so the ignition must be on for them to work.

If you have power reaching the switch, simply by-pass the switch by bridging between the two contacts.  If that makes the lights work then the problem lies in the area of the switch.  Check the operating mechanism is working properly and, if it is, then it is probably the switch itself at fault.

If by-passing the switch does not make the lights work, then check for power at the lamps.  If power is reaching the lamps and the side lights are OK then it is unlikely to be the earth but still worth checking.

Good luck.
