In the event of a power loss at the control tower, using a spotlight is a method of communication to ensure continued operations and safety at the airport. The spotlight signals are typically directed toward aircraft operators and ground service equipment operators, as they play critical roles in managing ground movements and the safe operation of the aircraft involved.

Aircraft pilots need clear and concise information about runway and taxiway conditions, as well as instructions when in the vicinity of the airport. Ground service equipment operators also rely on communication to perform their functions safely, coordinating the arrival and departure of aircraft, fueling, and other essential services. The spotlight serves as a visual cue for these personnel to inform them of necessary instructions or warnings during a power outage when standard communication methods are compromised.

While communicating to other ATC towers and motorists on the airfield can be important in various contexts, the immediate and critical reliance during a power failure pertains directly to those operations on the ground in proximity to the aircraft.
