The car is a 1995 Pontiac Firebird. The dual filament brake/turn signal lights are very dim on my car. I'm reading between 2 and 6 volts for all four of them when it is just the turn signal on and no other lights. The far outside tail light is reading 12 volts. I checked the voltage at the connector before the wires route to the dual filament bulb sockets and the voltage was close to 12.
I am thinking the sockets are not healthy anymore. Is there anything else I should check?
Below is a diagram. I am talking about the #6 sockets/bulbs. All four of them are giving low readings.
