A conspicuity enhancer includes a case defining an optical cavity having an output optical window. The conspicuity enhancer also includes first and second linear light sources forming a V. Each linear light source has a light emitting device that inserts light into one end of the light source. The other end of each light source is attached to the case such that each linear light source is in optical communication with the optical cavity.
