Looks exactly like the dimmer circuit in my old Arrow. Had to replace those NPN transistor several times along with a string of grounding issues. When the pot is at minimium R you get full bright on the lights and when the pot is adjusted you modify the bias on the base of Q1 or Q2 dimming the lights.
