ABSTRACT:
An improved barrier light assembly is provided of the type wherein the lens subassembly is pivotable relative to the case subassembly. The assembly employs a limited field light source (preferably an LED with a field of about 34.degree.), and incorporates a self-orienting, lens coupled holding and positioning subassembly for such a light source whereby this light source remains fixed at the lens subassembly focal point with its emission center line extending along the lens center line regardless of the pivoted position of the lens subassembly.
