4 position light switch on my 1939 120.

Can some one explain the function of the 4 position light switch and how the dimmer switch relates in the actions.
Someone converted my car to sealed beamed and rewired the lighting circuit with a all green wire color wire.
Does the dimmer just act on the high beam by cutting out just one headlight?
