Magnetically attached lighted sign

Image Number 2 for United States Patent #6955455.

A lighted sign for application to a vehicle surface includes first and second metallic layers with a magnetic plate sandwiched therebetween. The second metallic layer includes a circumference smaller than that of the magnetic plate such that it is pressed against a vehicle surface when the magnetic plate is magnetically adhered thereto. A light source is coupled to the magnetic plate with a positive wire connected to the first metallic layer and a negative wire connected to the second layer such that the light source emits light when the first metallic layer is energized by a vehicle electrical power source and is grounded when the second metallic layer is pressed against the vehicle metallic surface. The magnetic plate and first metallic surface include cutouts so that light may be emitted by the light source therethrough. The lighted sign 10 include a microcontroller and environmental sensors for advanced lighting control.
