What is the protocol for lights usage while taxiing an aircraft?

The correct protocol for lights usage while taxiing an aircraft is to have the position lights and taxi lights turned on. Position lights are crucial for visibility, allowing other aircraft and ground personnel to see the aircraft during taxi operations, especially in conditions of reduced visibility. Taxi lights are designed to provide improved illumination of the taxiway, assisting pilots in safely navigating the airport environment.

Having these lights on enhances safety by increasing the aircraft's visibility to others and ensuring that the pilot has sufficient lighting to see any obstacles or markings on the runway and taxiways. This practice is standard across aviation to mitigate the risks associated with ground movements.
