Instrument Panel Question

Trying to clean up some wiring issues today and discovered next to my temperature gauge and on the other side next to the gas gauge are two circular indicator lights. One says "TAND'M LOCK" and the other side says "OVER SPEED". Anyone know what these were for? Second question is did all 66 models have reverse lights?

Re: Instrument Panel Question

The "tandem Lock" and "Over Speed" were for the heavy trucks like C40 and bigger. They just made instrument panels to fit them all, and just put lights in the necessary locations. I do believe that reverse lights were standard equipment in '66.
