Joe, you might find an answer here:rosecitythunderbirds.org

The brake light and tail light work fine. Just not the rear turn signal portion.  Joe-JDC

Check the grounds on the bulbs.

I am getting my '55 Thunderbird ready for the yearly state safety inspection and found the left rear turn signal not working.  The lights work, brake lights work, tag lights work, right turn signal works front and rear, but left turn signal front light comes on and stays on--no blinking, and left rear turn signal--nothing.  I have pulled the bulb and changed it, traced wires for any frayed or broken, none found.  Pulled the steering wheel and removed the turn signal switch to check it for proper actuation, seems to be ok. Flasher?  Ideas?   Joe-JDC
