The automobile lamp is a single tail lamp housing a single light bulb and a composite liquid crystal light valve configuration to provide all the necessary signaling functions.
This single automobile tail lamp apparatus, under the support from and the collaboration with Illume LLC, has a single light bulb and a liquid crystal (LC) light valve complex located near the light out-going facet. The combined operation of the light bulb and the LC light valve enables the single lamp to perform all of the required operations, as shown in the following pictures, i.e., "night on", "turning signal", "braking", "backing", "backing & turning", and "backing & turning & braking."
