78' KZ750 Stop lamp flashing

The stop lamp light on my dash is flashing and then goes solid when I press either brake. The running brake light is working but it does not illuminate when either brake is pressed.

The idiot light on the dash is triggered by the stop light outage unit. If the idiot light is flashing it means the brake light bulb has blown. 
Just replace the tail light bulb and it'll all go back to normal.
