Palm Beacon

A plam beacon circa 2371

A palm beacon is a flashlight-like device held in the palm of the hand, often used by away teams in dark areas. (TNG: "Booby Trap")

Palm beacons were used when away teams beamed down to the dark and foggy planet Tarchannen III. Susanna Leijten later advised turning off the beacons as the light was frightening the Tarchannen III species. (TNG: "Identity Crisis")

In 2368, Data modified a palm beacon to emit an optical burst pattern that would counteract the effects of the Ktarian game. (TNG: "The Game")

Deep Space 9's corridors were equipped with storage lockers (similar to weapons lockers) that held three palm beacons and two tricorders. (DS9: "Civil Defense")
