Abstract
An apparatus for producing light signals in a vehicle. The same physical apparatus produces light signals of two different colors. Light emitting diodes (LEDs) of two different colors produce diverging light rays. These rays are captured by a transparent plate and conducted to an edge of the plate, which reflects and collimates the light into parallel beams. The parallel beams then reach an elongated lens running along another edge of the plate, which focuses, or de-focuses, the light and transmits it externally as a signal.
