The Pila family of professional flashlights includes the GL2, GL3, GL4 and the new Codex for police/law enforcement/SWAT, security, EMS and military. The Codex can be installed into the Pila flashlight from Electronic Services Agency and set to emit individual codes and signals, strobe, fade or dim output, and in emergencies can automatically release the SOS code. Users can also set different light intensities to save battery power or extend run time, release brief messages in Morse Code, and flare at different time intervals for team location and identification.
