An optical parking guide includes a container, a mounting element, either a laser diode or a light emitting diode and a control circuit. The mounting element is pivotally coupled to the container. The laser diode is disposed within the mounting element. The control circuit couples the laser diode to the garage door opener. The control circuit turns on the laser diode in response to the presence of a car with a front window and a dashboard so that the laser diode generates an output light. The mounting element directs the output light through the front window onto the dashboard of the car so that a driver of the car can guide the car into the car's parking place.
