OK.. to be clearer perhaps... and this might make more sense. If you are looking at a double filament bulb, one is for the brake/turn and the other is for the running light. There will be two feeds to the bulb, hot for the brake, and a hot for the run. There is no negative in the fixture, only a ground. So, my estimate of what you are measuring might be the voltage drop across the two filaments.
Have you taken the lens cover off yet to see what is going on with the actual filaments?
