The Schneider Electric GV2SN13 is a green pilot light from the TeSys range, designed as a local signalling indicator on motor starter enclosures or control panels. It mounts in a 17 mm diameter cutout with a flat round lens, giving a clear green status at a glance. Rated operational voltage is 110 V, using a neon lamp — so it draws minimal current and has a long service life, but it needs the full rated voltage to strike; it won't dim gracefully on a sagging supply.
Deployment context and protection
It's not submersible, but it handles the typical machine-side panel conditions without letting moisture creep into the indicator housing.
