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.

An organic light-emitting diode comprising an organic layer sequence, a radiation exit area and an encapsulation. The organic layer sequence comprises at least one radiation-emitting region which generates electromagnetic radiation in the spectral range from infrared radiation to UV radiation during operation. The radiation exit area is structured, so that the electromagnetic radiation has a directional emission profile. The encapsulation forms a seal of the organic layer sequence against environmental influences.

A vehicle system can include a plurality of portable devices, a vehicle, and a control system. The plurality of portable devices can be configured to be positioned variously about a scene. The vehicle can include a chassis, a cab coupled to the chassis, a body coupled to the chassis, a vehicle lighting device coupled to at least one of the cab or the body, and an aerial device rotatably coupled to at least one of the chassis or the body. The control system can be configured to control an operation of at least one of the vehicle lighting device, the aerial device, or the plurality of portable devices based on a position of the plurality of portable devices and the vehicle at the scene.

The present disclosure concerns a warning device comprising a warning body having a longitudinal axis and comprising a light-emitting assembly; and a collapsible stand configurable in a compacted configuration and in a warning configuration in which the light-emitting assembly is at least partially visible. The collapsible stand comprises a handle sleeve mounted to and slidable along the warning body and legs pivotably mounted to the handle sleeve, the legs being juxtaposed against the warning body when the collapsible stand is in the compacted configuration to cover the warning body and the legs extending outwardly and downwardly when the collapsible stand is in the warning configuration, the collapsible stand being configurable between the compacted configuration and the warning configuration by sliding the handle sleeve along the warning body. The disclosure also concerns a warning assembly comprising such a warning device and a method of emitting a warning light signal.
