Abstract: A digital display system designed to lie mounted on the exterior of a motorized vehicle, such as the front bumper of an automobile (see FIG. 1). The digital display system includes a monitor disposed within a frame secured to the vehicle. A controller is disposed within the passenger compartment of the vehicle. The controller interfaces with the monitor and includes removable memory for storing the data image files to be displayed on the monitor.

Abstract: An automotive lamp has a sealed envelope of barium silica glass that is essentially free of cadmium and in which a light emitting element is contained. Lead-in wires extend through the envelope and are coupled to the light emitting element. The glass envelope and lead-in wires have respective coefficients of thermal expansion over a temperature range form ambient to 520° C. which closely match one another to minimize stress and cracking of the envelope at the interface.
