Abstract
A motor vehicle alerting bright light dimming message display system for requesting a driver of a vehicle behind the vehicle displaying the message to dim his bright lights. The message display system improves vehicle safety and promotes driver courtesy. The message display system may include an LED or LCD display at the rear of a vehicle and a control circuit for operating the display. In one aspect of the invention, the display is automatically activated by a bright light from a trailing vehicle. The digital message display for vehicles detects a bright light intensity exceeding a threshold and automatically displays a request, directed to the driver of the trailing vehicle, to dim lights. The display may also be configured to display advertising, emergency and other messages.

In a motor vehicle, a system for requesting a driver of a vehicle behind another vehicle to dim his bright headlights comprising:
- at least one digital message display mounted on the rear of a vehicle, said digital message display being adapted to display a digital message for requesting a driver who is operating a vehicle behind the requesting vehicle to dim his vehicle's bright headlights;
- and a power supply for supplying electrical power to said digital message display.
A digital message display for vehicles comprising:
- a message display capable of displaying short textual messages, the message display being adapted for mounting in or on a first vehicle and thereby being viewable by a second vehicle behind;
- at least one bright light sensor, the at least one bright light sensor being adapted for mounting in or on the first vehicle and thereby being subject to bright light incidence of the second vehicle;
- a microcontroller in electrical communication with said message display and with said at least one bright light sensor;
- and
- non-transitory computer readable media accessible to said microcontroller, the media storing microcontroller program instructions for determining bright light incidence on at least one bright light sensor and instructions for selectively displaying on said message display a predefined short textual message in response to the determination.
