The DIALIGHT MS25010C16B is a classic panel mount indicator designed for front mounting in MIL-P-7788 plastic panels. It utilizes a translucent panel edge lighting system to emit light through a colored filter into the plastic plate. A light seal washer ensures minimal light loss. This indicator meets applicable requirements of MIL—L7806, MIL—L—3661B & MS25010 — Revision D. It features a brass mounting bushing with a cadmium plated finish, internal-tooth lockwasher and hex nut, and solder terminals with a hot-tinned finish. The shank of the lens holder is crimped for lamp security.
