What are the red and green lights for?

Red and green lights have been a part of 25m pistol systems for decades, indicating to athletes when to shoot during timed and rapid fire events. We decided to include them in the NC100 for 10m rifle and pistol for a few reasons, and primarily for safety. Young athletes who are new to the sport may not be familiar with all range commands. Now with the red light, the “STOP” command becomes both audible and visual.
