A vehicle warning sign comprises: a reflective material for at least visible light; and at least one of (i) a heating element for detection by a thermal sensor or (ii) a corner reflector for detection by a radar, the corner reflector oriented substantially in a common direction with the reflective material.

A three dimensional truck or SUV cab marker light apparatus comprising a container having a right circular cylinder structure with a shape determined by the number of walls used during assembly, each wall being formed from a generally flat sheet of a rigid material and a transparent material, the walls being assembled to form a container enclosing an interior region for a light-transmission source and having a lower surface for attachment to a cab roof without drilling holes into the cab roof and without installing wires through the cab roof.

A lighting element includes a circuit board defining a longitudinal axis and including at least one illuminator thereon, a housing having at least one flexible element in the optical pathway of the at least one illuminator and in register with the at least one illuminator on the circuit board, and with opposing axial ends.

A housing for connecting a light bar to a vehicle comprises at least a front surface comprising a lighting aperture, a first side surface, a second side surface opposite the first side surface, and a top surface defining a hollow interior. The housing further comprises at least a first bracket and a second bracket located within the hollow interior. The first bracket is configured to connect a first interior face of the housing to a first side of the light bar while the second bracket is configured to connect a second interior face of the housing to a second side of the light bar. At least a portion of at least one of the front surface, the first side surface, the second side surface, the first bracket, and/or the second bracket is configured to connect to a surface of the vehicle.

An electronically controlled motor driven siren. The siren is electronically controlled to generate different sound profiles, while having advantages of a motor driven mechanical siren. In some embodiments, the siren is part of a system of multiple sirens. The phases of the rotors of the sirens of the system can be electronically controlled to generate different multi-siren combined sound profiles.

An illumination system and method of ground and other illuminating that comprises a plurality of sensors that scan/detect the exterior area around the vehicle and at least one controller, the system selectively turning on/off a series of lighting elements placed strategically around the vehicle to allow light to be directed to at least one ground or other surface at the persons at all times or any predetermined time. A controller is provided to activate ground lighting in coordination with sensor signals identifying where an individual or object are located in predetermined proximity to the vehicle.

A system includes a tracking system, a controller-circuit, and a device. The tracking system is configured to detect and track an object, and includes one or more of a computer vision system, a radar system, and a LIDAR system. The controller-circuit is disposed in a host vehicle, and is configured to receive detection signals from the tracking system, process the detection signals, determine, whether an object is detected based on the processed detecting signals, and in accordance with a determination that an object is detected, output command signals. The device is adapted to be mounted to the host vehicle, and is configured to receive the command signals and thereby provide a dynamic visual indication adapted to change in accordance with orientation changes between the host vehicle and the object. The dynamic visual indication is viewable from outside of the host vehicle.

A vehicle may include a movable roof, a sensor supported by the roof, and an actuator for selectively raising and lowering the roof.

A roof panel assembly for use in a roof of a vehicle comprises at least one roof panel, providing a first interior surface configured to be directed to an interior space of the vehicle and a second interior surface configured to be directed to the interior space of the vehicle. The roof panel assembly further comprises a support beam arranged between the first interior surface and the second interior surface and a projector device arranged on the support beam. The projector device is configured to project a light image on at least one of the first interior surface and the second interior surface.

A vehicle includes a chassis, a driveline coupled to the chassis, and a control system. The control system is configured to monitor a condition of at least one of the vehicle, an area around the vehicle, or an operator of the vehicle; and control operation of the driveline based on the condition. Controlling the operation of the driveline includes at least one of limiting a speed at which the driveline drives the vehicle or shutting down the driveline and isolating a component of the driveline.
