An edge-emitting light bar assembly for a vehicle includes a light-transmitting, edge light-diffusing optical fiber and an at least partially light-transmitting extruded or pultruded coating surrounding the optical fiber to provide a single-layer coated optical fiber. At least one light source is provided for emitting light rays to impinge on an end of the optical fiber. A housing connected to an end of the coated optical fiber and surrounding the at least one light source is provided. The light bar assembly may include a light source disposed at each opposed end of the optical fiber. The single layer coating may include one or more of a colored tint or dye, a frosted material, and a plurality of light reflective or refractive inclusions. Optionally, a portion of the single-layer coating includes an opaque material disposed to direct emitted light rays in a predetermined direction relative to the optical fiber.
