Sensors coupled to a first vehicle are used to measure sensor measurements. Based on the sensor measurements, the first vehicle identifies a risk to the first vehicle and/or to a second vehicle near the first vehicle, for example based on a distance between the first and second vehicle being unsafely low. The first vehicle generates an alert based on the risk and outputs the alert toward the second vehicle, for example visually through a screen and/or audibly using speakers, to warn an operator of the second vehicle about the risk.

A vehicle state alert apparatus is used in a vehicle including a vehicle exterior alert apparatus capable of making an alert to a person outside the vehicle, and includes: a state determiner that determines a state of a driver of the vehicle and a state of the vehicle; and an alert controller that causes the vehicle exterior alert apparatus to make a state alert for communicating the states determined by the state determiner. The states determined by the state determiner include a first state in which an emergency situation is likely to occur and a second state in which the first state is likely to occur, and the alert controller controls a travel state of the vehicle in accordance with the states determined by the state determiner.

System, methods, and other embodiments described herein relate to alerting a passenger about hazards when exiting a subject vehicle. In one embodiment, a method includes identifying an initial target and a subsequent target according to sensor data about a surrounding environment of the subject vehicle. The method includes, in response to determining that the initial target satisfies an alert threshold, activating an initial alert for a defined time to inform the passenger of a hazard associated with the initial target and the passenger exiting the subject vehicle into a path of the initial target. The method includes extending the defined time responsive to the subsequent target satisfying the alert threshold and a timing threshold that defines a cool-down period between activating separate alerts.

A motor vehicle horn and light system accommodating sounding a vehicle horn and illuminating one or more vehicle exterior lights when a user-operated button is pressed. The electrical circuit includes a battery electrically connected to a horn and light system computer. The system computer includes a processor and an input/output interface. The system circuit further includes a user-operated button electrically connected to the battery, to a vehicle horn, and to an input port of the system computer. The system computer is electrically connected to a light relay module via an output port, and the light relay module is connected to a vehicle exterior light. The system computer processor can be programmed to illuminate or flash the exterior light as desired. The system may further include a horn and light system switch and may also include a vehicle main computer electrically connected to the light relay module.

A U-turn signal indicator system for a vehicle includes an indicator assembly including a first portion that may have a first color, and a second portion configured to form a symbol for a U-turn. The second portion may have a second color that contrasts with the first color. The U-turn signal indicator system may further include a light emitting element configured to illuminate the first portion and the second portion, and a control device configured to activate the light emitting element.

A lighting device equipped at all times in a vehicle, which can be used for camping and leisure and has a function of a safety warning light of the vehicle, according to the present invention, comprises: a rectangular-shaped fixing plate having a pair of first magnet members which are disposed horizontally; a “C”-shaped front insertion groove which is formed on the front surface of the fixing plate and is formed to be adjacent to the edges of the fixing plate excluding the upper or lower edge of the fixing plate; a “C”-shaped first support member which is selectively fixed to the front insertion groove and is installed rotatably toward the front surface with respect to the fixing plate by the medium of a hinge; a pair of side surface insertion grooves which are longitudinally formed on the respective sides of the fixing plate; a pair of second support members which are respectively coupled to the inside of the side surface insertion grooves by the medium of a hinge, and are unfolded in a direction opposite to the first support member; a light unit which has, on the rear surface thereof, a second magnet member coupled to the first magnet members, has a battery embedded therein, and has a lighting device on the front surface thereof; and a cover which is rotatably coupled to the light unit by the medium of a hinge so as to selectively cover the lighting device, wherein the lighting device may flicker when the lighting device is covered by the cover.
