Alerts Sign-up
Aircraft are equipped with a variety of lights to enhance visibility and ensure safety during operations. Commercial aircraft typically have more than the mandatory four types of lights, which include landing lights, beacon lights, strobe lights, and position or navigation lights.
Beacon lights, also known as anti-collision lights, indicate when an aircraft is in operation. Historically rotating, modern beacon lights use LEDs that emit a longer red flash compared to older Xenon models. These are positioned on top of the tail and alert ground crew when engines are about to start. Beacon lights must be active during taxiing, takeoff, and throughout the flight.
Strobe lights are another essential feature for collision avoidance. Positioned on wingtips, these white flashing lights increase aircraft visibility at night and must be used from runway entry until after landing. As per FAA regulations under 14 CFR 91.209(b), if installed, these systems should be operational day or night unless deemed unsafe by pilots.
