The light exoskeleton served as light armor, operating as a power-assisted exoskeleton. By replicating the wearer's primary muscle actions with mechanical forces, it amplified their strength and improved their reflexes. This armor was a more recent development during the era of the Jedi Civil War, specifically around 3956 BBY. Suvam Tan, a male Rodian residing in the Yavin Station that orbited Yavin Prime, possessed a suit of this armor.
The light exoskeleton made its debut in Star Wars: Knights of the Old Republic, the roleplaying game from 2003. Visually, it was the same as the Electromesh suit featured in the 2004 follow-up, Star Wars: Knights of the Old Republic II: The Sith Lords.
