Brake Lights Quit Working

[donerehart]

Just took my 76 out for a night ride and discovered that my brake lights no longer work - not sure when they stopped working either. All of my other lights are working... Where should I start with this challenge?
Thanks,

bulbs, brake light switch, fuse

I would start by making sure the connectors are making good contact at the rear tail-light circuit boards.
Unplug them and plug them back in.
See if that fixes it.
If not, I would look at the brake-light switch at the brake pedal. It can be tested with an ohmmeter with the wires disconnected from it.
Also, take a look at the fuses to make sure they are all ok.
If both brake lights are not working, I would bet the problem is one of the above-mentioned items.

Thanks so much...if one brake light quits working, will they both quit working?

Not sure on a 76.
On my 80, if the left circuit board connector is not secure, it will affect both the left and right lights.
The right light is wired off of the left light connector.

The brake light switch was bad...what a bugger it is to get out of there! Thanks for your help!
