Devices, systems, and methods are provided for enhanced sensor cleaning validation. A device may determine a baseline performance measurement associated with a clean performance baseline of a sensor. The device may actuate a cleaning mechanism to remove at least a portion of an obstruction deposited on the sensor. The device may determine a first post-clean performance measurement associated with the sensor. The device may determine a degradation measurement between the baseline performance measurement and the first post-clean performance measurement, wherein the degradation measurement indicates an effectiveness of the cleaning mechanism.

Systems and methods for a remote vehicle light check of a host vehicle having a plurality of lights is provided. In one embodiment, a method includes detecting a lighting check signal at a host vehicle having lights. The lighting check signal is received from a trigger device. The method also includes triggering a light sequence in response to the lighting check signal being detected. The light sequence causes one or more lights of the plurality of lights to be activated. The method further includes activating the one or more lights based on the light sequence. The method further includes pausing the activation of the one more lights by a predetermined delay.

A multi-purpose vehicle includes a load carrier deck supported to a vehicle body frame which is supported on a ground surface via front wheels and rear wheels. The load carrier deck includes a deck constituting unit having a bottom plate, a left wall, a right wall, a front wall and a rear wall. A lamp for illuminating inside of the load carrier deck is provided in the deck constituting unit.

Various embodiments include methods and vehicles, such as an autonomous vehicle, a semi-autonomous vehicle, etc., for collaboratively directing one or more headlights among vehicles traveling in a platoon. Various aspects may include transmitting, by a first vehicle processor of a first vehicle traveling in the platoon, a collaborative lighting plan to a second vehicle traveling in the platoon, wherein the collaborative lighting plan may direct the second vehicle to direct one or more headlights of the second vehicle in a direction other than a direction of travel of the platoon. The first vehicle processor may then direct one or more the headlights of the first vehicle in accordance with the collaborative lighting plan.

To promptly detect a failure of a light source. A vehicle headlight system includes a plurality of light sources, a power supply supplying a drive voltage to the light sources, a controller individually controlling a lit/off state of each light source, and a failure detection circuit connected to the controller and detects a failure of the light sources, where, in response to a start of the vehicle, the controller executes a control operation in which all light sources are controlled from the off state to the lit state and then the light sources are controlled to the off state sequentially and individually, and where, while the control operation is executed, at least during the period of transition from the off state to the lit state of each light source, the controller acquires failure detection result and generates a warning signal when the failure is detected.

The present disclosure provides an LED straight light including a light tube with two pins at both ends, an LED installed in the light tube and a driving circuit. The driving circuit includes a mains branch and a signal branch. The mains branch is coupled to the pins at one end of the light tube for transmitting power to the LED for power supply. The signal branch is coupled to the pins at the other end of the light tube for transmitting external driving signals to control the on/off of the mains branch. The LED straight light of the present disclosure is powered by two ends, one of the two ends supplies power to the LED through the mains branch, and the other end receives driving signals to control the on/off of the mains branch.

A lighting device may comprise: a flexible lighting module having a light emitting device; a coupling member arranged on the lower portion of the lighting module; and a bracket comprising a receiving groove in which the lighting module is received and having a coupling hole formed therein such that the coupling member is inserted and coupled thereto.

An abnormality detection apparatus, comprises a first acquisition unit configured to acquire imaged data obtained by imaging an object vehicle traveling on a road; a first recognition unit configured to recognize a lighting state of lighting devices of the object vehicle, based on the imaged data; a second recognition unit configured to recognize a lighting necessity of the lighting devices, based on the imaged data; and a detection unit configured to detect whether the lighting devices operate normally or abnormally, based on the lighting state and the lighting necessity.
