Abstract: An illuminated, inflatable mast assembly positioned at a site and deployed for warning on-coming drivers of vehicles of the location of the site.

Abstract: A junction box assembly for a light bar for splicing a light bar cable and a vehicle cable. A multipart housing forms a compartment and has at least two separable parts for accessing the compartment. The compartment is configured for receiving an end of the light bar cable and for receiving an end of the vehicle cable. The multipart housing is configured to mount externally and slidably to the underside of the light bar.

Abstract: A bezel for a light fixture appears illuminated when a bezel light source is energized and the bezel appears opaque when the bezel lights source is not energized. The bezel has a metalized coating which reflects light transmitted from a location remote from and external to the bezel and which transmits light emitted by the bezel light source.

Abstract: A solar light bar includes a battery isolator adapted to be connected between a bus and a vehicle charging system for isolating a vehicle battery from the bus and for selectively connecting the bus to the charging system. A light source switch connects the light source and the bus for selectively electrically connecting the light source to the bus. When the light source switch is closed, the light source is energized by electricity from at least one of the solar panel, the charging system and the auxiliary battery. When the light source switch is open, the light source is isolated from the bus. The auxiliary battery is adapted to be selectively charged by electricity from at least one of the solar panel and the charging system.

Abstract: A light bar and/or a siren controlled by a control head via control signals on power lines connected to the control head, the light bar and/or the siren. Isolated power line communication (PLC) modules between the light bar, the siren and the control head transmit the control signals over the power lines.

Abstract: A wireless interface module is used with at least one of a light bar, a control head, and/or a siren so that a mobile device can wirelessly control the light bar and/or siren via a user interface.

Abstract: An interior light assembly for use in a vehicle includes a housing having a light transmission end constructed to pass light out of the housing. A light source is located in the housing and arranged to emit light in a direction to pass out of the light transmission end of the housing. A visor extends from the light transmission end of the housing for blocking light from the light source in directions transverse to the light transmission end of the housing into a passenger compartment of the vehicle. The visor has an end remote from the housing shaped to engage a windshield of the vehicle. The visor may be pivotably mounted on the housing to facilitate flush engagement of the remote visor end with the windshield. The visor can flare outwardly from the housing to the remote end so light can be seen at greater off-angles by persons outside the vehicle.

Abstract: A light bar may include a light head with chip-on-board (COB) light emitting diode (LED) and an optic component mounted adjacent to the COB LED. The light bar may comprise short and long center modules. The light bar may include a plurality of housing modules where each housing module includes a light head and a lens cover having a top portion that is substantially impervious to ultraviolet radiation, and a lens portion extending downward from the top portion in generally opposing relationship with the light head. The light bar may include a circuit board including a wire-to-board connector, and a light head including a wire-to-board connector mated with the wire-to-board connector on the circuit board to electrically connect the light head to the circuit board. The light head may include a holographic diffuser.

Abstract: A light head for a light bar and/or an emergency vehicle light includes a light mixer with diffuse reflectivity, a blue light engine and a phosphor impregnated light optic. Blue light from the light engine causes the phosphor to fluoresce and emit colored light having a wavelength different that the wavelength of blue light of the light engine.

Abstract: A system comprising a power supply, an emergency warning light and a speaker, in combination with a control head. One or more processors controls operation of the system in response to received user input and provides system status for display. Storage media encoded with emergency warning light system instructions for execution by one or more of the processors controls the actuation of the emergency warning light system and controls light patterns generated by the emergency warning light system. The storage media is further encoded with siren system instructions for execution by one or more of the processors for controlling the actuation of the siren system and for controlling audible sounds generated by the siren system.

Abstract: A light module for a side mounted rear view mirror of a vehicle includes a light and an electrical conductor for connecting the light to a power source through an opening to be formed in a forward facing surface of the rear view mirror housing. The module includes a boot having an opening at a front end and a flexible back end. A fastening system is adapted for mounting the light and boot on the forward facing surface of the rear view mirror housing so the flexible back end of the boot is compressed against the forward facing surface of the mirror housing and a segment of the electrical conductor extending from the opening in the forward facing surface of the rear view mirror housing is substantially enclosed in the boot when the light module is installed on the rear view mirror.
