Abstract: A searchlight system for mounting to a vehicle, for example on the A-pillar, without requiring modification to structural frame components. The system comprises a mounting assembly which is installed on the vehicle and a searchlight assembly which is mounted to the mounting assembly. Searchlight assemblies with different optical devices can be modularly exchanged with respect to the same mounting assembly installed on the vehicle. Also disclosed is a method for installing such systems. Other aspects are directed to heat dissipation and ingress protection for the searchlight assembly.

Abstract: A battery charging station having a main docking station to recharge the battery while the battery is installed in a electrical device and a second charging station that can be removed from the main base is disclosed. The removable charging station allows a user to charge a battery not in use at a remote location from the docking station. If the second charging station is attached to the docking station, the battery in the removable charging station is charged after the battery installed in the light is charged.

Abstract: A railroad car-warning bell is centrally mounted on the hub of a wheel. Three opposed cylinder housings each contain a reciprocating ball which hits an end hammer to sound the bell when the wheel turns slowly up to speeds of nominally 15 mph. At higher speeds the balls are held against the end hammers, thereby automatically shutting off the bell to prevent noise pollution. The preferred embodiment has a single cylinder mounted along a diameter of the ringing bell. Three steel balls oscillate back and forth hitting a hammer at each end of the cylinder. A dampener may be used to adjust the ring of the bell.

Abstract: A portable searchlight includes an upper lamp housing, a lower base support unit and a releasable attachment device to releasably attach the base support unit to another surface, such as, the roof of a motor vehicle; and the apparatus and specifically the lamp housing can be tilted or rotated by remote-control from the interior of the vehicle. The releasable attachment device is such that the apparatus can be secured by a suction cup or by placing the base support unit in a shoe which is anchored to another surface.
