ABSTRACT:
A telltale is sufficiently small and sufficiently bright for use in a head-up display such that the image of the telltale is projected of the combiner, e.g., the vehicle front windshield, and is clearly visible to the vehicle operator, even on bright sunny days. The apparatus includes a housing and a light source. The housing has an inner reflective surface with a focal point outside the housing and an aperture located between the reflective surface and the focal point. A graphics plate is mounted in the aperture. The telltale is highly emissive when light from the light source reflects off of the inner surface and through the aperture.
