I was getting my '55 T-bird ready for annual inspection, and when I checked the lights, the left brake light in the rear did not work, and the left rear turn signal does not work.  The light does come on when the headlights are pulled on.  I have checked the bulb, the wiring, and don't see anything at the rear that looks like the culprit, so I am checking forward to the firewall.  Any ideas?  The front turn signal light comes on but does not blink when the left turn signal lever is actuated.  The inside indicator comes on but does not blink.    Thanks in advance.  Joe-JDC
