A little closer view showing H&F RR No 172 with the electric headlamp and trolley pole reel mounted on the front of the car. The headlights were removable and hung on bracket with a wire that plugged in to a jack on the end of the car. When the trolley got to its destination the driver would take the headlight off and move it the other end for the return trip. He also lowered the trolley pole and raised the one at the opposite end for the return trip.
