Abstract
Abstract A concealed vehicle lamp assembly includes an energizable bulb and an exterior lens cover of transparent material aligned with an interior lens to intercept ambient light from the exterior lens and associated with means to reflect a first color through the exterior lens when the bulb is deenergized. The interior lens includes means for directing a second color through the exterior lens when the bulb is energized.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
176 words
A concealed lamp assembly for association with contiguous panel structures of vehicles comprising a housing having an exterior lens of light transparent material, an interior lens of light transparent material having a semi-transparent light reflective metallic coating facing the exterior lens, a colored surface interposed between said interior and exterior lens to receive outside ambient light from said exterior lens, said interior lens being disposed angularly with respect to said exterior lens and said colored surface to reflect an image of said colored surface from said coating through said exterior lens to cause said interior lens to appear opaque under ambient light conditions and to produce a first apparent lamp light color when the lamp is not illuminated, a lamp and reflector for illuminating the interior lens to direct light from said exterior lens when the light is energized to produce a second apparent lamp light color when the lamp is illuminated, said semi-transparent coating further serving to intercept outside ambient light directed at said reflector and redirect such intercepted light when said lamp is deenergized.
Claim 2
Dependent Claim
176 words
A concealed lamp assembly for association with contiguous panel structures of vehicles comprising a housing having an exterior lens of light transparent material, an interior lens of light transparent material having a semi-transparent light reflective metallic coating facing the exterior lens, a colored surface interposed between said interior and exterior lens to receive outside ambient light from said exterior lens, said interior lens being disposed angularly with respect to said exterior lens and said colored surface to reflect an image of said colored surface from said coating through said exterior lens to cause said interior lens to appear opaque under ambient light conditions and to produce a first apparent lamp light color when the lamp is not illuminated, a lamp and reflector for illuminating the interior lens to direct light from said exterior lens when the light is energized to produce a second apparent lamp light color when the lamp is illuminated, said semi-transparent coating further serving to intercept outside ambient light directed at said reflector and redirect such intercepted light when said lamp is deenergized.
Claim 3
Dependent Claim
174 words
A concealed lamp assembly for association with contiguous panel structures of vehicles comprising a housing having an exterior lens of light transparent material, an interior lens of colored light transparent material having a semi-transparent light reflective metallic coating facing the exterior lens, a colored surface interposed between said interior and exterior lens to receive outside ambient light from said exterior lens, said interior lens being disposed angularly with respect to said exterior lens and said colored surface to reflect an image of said colored surface from said coating through said exterior lens to cause said interior lens to appear opaque under ambient light conditions and to produce a first apparent lamp light color when the lamp is not illuminated, means for illuminating the interior lens to direct light from said exterior lens when the light is energized to produce a second apparent lamp light color when the lamp is illuminated, said semi-transparent coating further serving to intercept outside ambient light directed at said reflector and redirect such intercepted light when said lamp is deenergized.
