Abstract
The device includes a visible light source and a transmissive/reflective layer on a vehicle. The layer is between the source and an observer and transmits emergency warning signals of various colors to the observer. In addition, the layer reflects ambient light so that when the light source is not illuminated the appearance of the device is changed and the emergency warning colors, if any, of the device are masked.
