How to turn on the work light in Lumber Tycoon 2
Every Worklight has a toggle button on its left side. Click it once: the button turns green and the lamp starts emitting light. Click again to switch it off (the button turns red).
Wiring the Lumber Tycoon 2 worklight to a switch
To control lights from one place, buy a lever and a Simple Wire. Connect the wire from the lever to the Worklight — flipping the lever now turns the light on and off. You can chain more wires to control several lights.
