1.7

CONSTRUCTION

The SM-2 Light essentially consists of a case with a battery, switch, electric circuit, flashlamp,
globe, lanyard attachment flange, a mounting bracket, and a buoyant, non-absorbent unicellular
polyfoam, used as filler material.
1.8

LANYARD

The size, weight, and shape of the light are suitable for conveniently throwing overboard, while
attached to a life ring buoy by means of a lanyard. A hole is provided in the bottom flange of the
case for lanyard attachment.
1.9

CASE

The case is made of a high-impact plastic; International Orange in color, which is constructed to
receive all components necessary to produce the required light output. No additional signaling
devices are incorporated in the unit. An attachment point for lanyards is provided on the side of the
case opposite the globe. It can be used to attach a life buoy ring.
1.10

LENS

The lens is made of a colorless, polycarbonate plastic (lexan) which is free mechanical defects
which would impede its primary function of radiating light. The Lens is of such design as to
withstand all impact tests that are required in this application.
1.11

BALLAST

Ballast consists of a metallic weight permanently secured in the bottom of the case.
1.12

MOUNTING BRACKET

The mounting bracket is designed to hold the light in the inverted position and prevent free
movement of the light when properly secured within the bracket. The bracket is made of a
corrosion-resistant plastic and is arranged for mounting on a vertical surface.
1.13

DIMENSIONAL STABILITY AND VAPOR PROOFNESS

The SM-2 Light is capable of undergoing specified temperature humidity cycles with no signs of
shrinkage or distortion which might impair its serviceability, watertightness or vapor proofness.
The watertight integrity of the equipment is assured by O-Ring seals between surfaces. The unit's
ability to withstand any anticipated external forces is assured by the combination of material
strength and assembly methods.
