I believe that prior to the 24th series instrument lights had a separate switch. They were powered from the headlight switch so operated only when that was on. In some years or models the instrument bulbs were infinitely variable by turning a rheostat and in other years they had discrete brightness levels where they were just on or in some instances a rotary or push pull switch also selected a fixed resistor for two or three briteness levels.

With the 24th series onward they combined the instrument light rheostat with the headlight switch and as an extra added attraction they also provided in the headlight switch an on/off function for the driver to control some of the courtesy lights. Which set of bulbs were controlled was determined by the direction the knob was turned.
