On the 1972 stock i noticed the lights do not work ( cablight and headlights ) They are on but they do not light up the cabin or the Underground tunnels
For the headlights they are not built for illuminate at long distance but for other drivers/passengers to see you specially at night
I remember that the headlights would light up the tunnels a very very small amount, but i could be wrong Still strange that the cablight does not funtion at all
