Abstract: A vehicle positioning apparatus (10) includes a sensor (34), light source (32) and adjustment mechanism (30). The light source (32) projects a light beam (192) toward a vehicle (196) when the sensor senses the operation of a garage door opener (16). When the vehicle (196) is in a desired parking location, the light beam (192) can be adjusted to hit a reference point on the vehicle. Thereafter, when pulling into the garage, the driver is signaled to stop when the light beam (192) reaches the predetermined reference point.

Abstract: A trailer light connection system includes a T-shaped connector having three terminals including a modularized tap plug as the third terminal for direct or indirect connection to the trailer lighting system. One of the conductors leading to the tap plug can be selectively disconnected from the first and second terminals and then reconnected to a ground receptacle on the vehicle to ground the trailer to the towing vehicle when the trailer does not have a back-up light system. By standardizing the system components and modularizing the tap plug connections, the trailer light system of the present invention reduces the number of stock keeping units required while simplifying system installation.

Abstract: A system and method for checking the aim of the high and low beams of a vehicle headlamp are provided. The system comprises a vehicle position locator adapted to be centered under the vehicle, and a target screen located at a predetermined distance from the headlamp of a vehicle centered on the locator. A laser/prism subassembly is mounted to the locator for lateral and vertical movement relative to the vehicle. The prism directs the laser beam toward the headlamp when it is positioned in front of the laser. A plurality of photosensors on the target screen sense the intensity of a light beam from the headlamp, and meters on the target screen indicate comparisons of the levels of intensity of portions of the beam sensed by the individual photosensors.

Abstract: An electrical connector for providing an insulation displaced connection between first and second insulated electrical wires includes a base and a cap. The base includes a body having at least one groove and a first electrical wire partially embedded in the body. A terminal pin on the end of the first wire extends into and is partially exposed within that groove. A second insulated wire is positioned in and extends through the groove, and the cap is positioned around part of that second wire adjacent the body. The cap is then matingly slid along the base, with a cam surface on the cap slidingly contacting the second wire to force that wire into an insulation displaced connection with the terminal pin on the first wire. When the cap is fully received on the base, the electrical connection is complete without any hand tools being used.
