The Pila family of professional flashlights include the GL2, GL3, GL4 and the Codex, ideal for Aviation use. The Codex offers unique features and options. The flashlight can be set to emit individual codes and signals, strobe, fade or dim output and in emergencies can automatically release the SOS distress code. It features quick installation and easy programming. With the Codex installed onto a Pila flashlight it can be programmed to: set different light intensities, emit short strobes for self-defense, attract attention by dimming and brightening at different timings, emit flashes for warning, automatically send off the SOS distress signal, and release brief messages in Morse Code.
