Opaque/Translucent Headlights

First attempted on my Large rear drive Ford project, but never implemented due to cost (although a Lincoln version would have likely utilized this). This takes the glass seen in some homes that can alter an LCD layer to go from opaque to clear and back. In this case the headlights are 'covered' until power is applied to turn them on, and then they appear. When off, they appear as black, making this a fit for grill applications. Downside is cost and low temperature performance delays for changing states.
