Check the brake light fuse. If you have 12 volts at the brake light switch I would suspect the signal light switch is at fault.

I would check the brake light switch first. It's a common problem. The switch is located down on the brake pedal and is easy to change. Use a 12 volt test light to check for power at the switch. You've changed the bulbs or checked for voltage at the brake light sockets first?
Yes. One switch is for the left and right brake light assemblies; and, the other is for the 'third' brake light.
Take hold of the brake light switch and pull backwards. The switch will come out in the same way that you would unplug anything. Plug the new switch in
The brake light switch on that bug would be found on the brake master cylinder. Remove the fuel tank to make access easier.
Check you brake fluid and the brake switch on the proportioning value. If the fluid level is ok then disconnect the switch to see if the light goes out. Also check the parking brake switch.
the brake light switch is out of adjustment. Readjust the switch.
Stuck brake light switch, or a short to power somewhere in the brake light circuit.
