This is a used GM turn signal light prism tab for 1979 1980 1981 Camaro
Unit attaches to the dash lens and reflects the light of the turn signal blinker.
When GM went to the 1979 1980 1981 bezel but used the same gauge cluster housing these were added as the dash bezel did not extend inward to the turn signal lamps. This brings the light out to the green arrow mounted on the dash bezel. Not reproduced.
