Greg:
Sounds like a bad bulb. The bulb has two filaments in it, and it
sounds like one has failed and is shorted to the other filament. Try
replacing the bulb, or swapping the bulbs from side to side to see if
the problem follows the bulb. Don't be surprised if the symptoms change
somewhat when you move the bulb as the broken filament will only make
intermittent contact to the good filament unless you have the luck of
the Irish.

Subject: [6pack] Left rear brake light problem
Hello List,
I have a right rear brake tail light problem that only occurs when the
cornering lights or head light switch is turned on. The right rear
brake light only works when the head light switch is off. When I tested
the voltage on the brake light wire when disconnected from the socket,
the voltage is present when the brake pedal is pressed while the
headlight switch is on and off. The socket checks out OK with the ohm
meter. The bulb contacts are clean. I tried a secondary direct ground
to the battery for the tail light assembly without success. There seems
to be another path of least resistance when the headlight switch is on.
Any thoughts or been there and done that? The TR6 has passed inspection
before with this problem because the inspector tested the brakes with
the head light switch off. Then turned on the headlight switch to check
the other lights.
