ABSTRACT:
A safety device for use with a vehicle such as an automobile or the like which provides a driver actuated signal for visually indicating to a following vehicle driver that the leading vehicle is seeking and/or is about to maneuver into a parking area. This provides adequate notice to the driver of the vehicle following so that the following vehicle may be maneuvered safely around the parking vehicle to allowing the parking vehicle to more readily maneuver into a parking space. The device includes an illuminated display which is mounted on the rear of a vehicle, a power source and a switching circuit controllable by the driver to activate the display regardless of whether the vehicle is in forward or backward motion or is stopped. The switching circuitry is connected to the conventional left and right turn signal lever and switch and is activated by fast sequential movement of the turn signal lever (left to right or right to left) causing the parking alert display to blink, bypassing the normal left and right turn signals. The parking alert display will continue to blink or be illuminated until the ignition key is turned off.
