    Anti-collision lights, also called beacon lights or strobe lights, are a set of lights required on every aircraft to improve visibility to others, as well as collision avoidance measures by warning other pilots. [1] Historically they have used incandescent light bulbs, but recently LED lamps have been used.

    In the case of a radio failure or aircraft not equipped with a radio, or in the case of a deaf pilot, air traffic control may use a signal lamp (called a "signal light gun" or "light gun" by the FAA [1] [2]) to direct the aircraft. ICAO regulations require air traffic control towers to possess such signal lamps.

    HID lamps have also become common on many aircraft as replacements for traditional landing and taxi lights. [citation needed] HID lamps are also used in lamps for underwater diving. The higher efficacy of HID lamps compared to halogen units means longer burn times for a given battery size and light output.
