The present disclosure relates generally to safety lighting devices for automotive vehicles. A safety lighting system coupled to an automotive vehicle includes a power source that is independent of an electrical system of the vehicle. The system also includes a lighting feature electrically coupled to the power source, wherein the lighting feature is configured to activate in response to an impact event.

An apparatus controls the forced light up of brake lights. The apparatus checks whether a brake light system has problems to prevent vehicle rear-ending accidents. A driver is informed, according to a state of a vehicle, about each problem. When there is a breakdown of the brake light system, such as a brake lights fuse disconnection, a breakdown of a brake lights relay, a wiring disconnection or defective wiring contact or the like, the driver is informed of the breakdown. Then rear vehicle is informed of danger by flickering a turn signal light since the brake lights do not light when the brake light system and the brake lights have broken down. The driver is informed of the breakdown of the brake light system and the brake lights by operating an internal alarm means whenever the driver steps on and releases the brake, thereby enabling the driver to drive safely.

Techniques for drone device control are provided. In one example, the technique includes monitoring, by a drone device operatively coupled to a processor and allocated to a vehicle in operation, one or more conditions associated with the vehicle. The technique also includes, in response to identifying, by the drone device, a defined condition of the one or more conditions: moving, by the drone device, to a position relative to the vehicle and determined based on the defined condition; and performing, by the drone device, an indication operation determined based on the defined condition.

A light emitting element driving device includes a first and second driving circuits, an abnormality detecting portion, a bypass path, and a switching portion. The first driving circuit can supply power to a light emitting element in a first mode, and is disabled to supply power in a mode other than the first mode. The second driving circuit can supply power to a light emitting element in a second mode. The abnormality detecting portion detects an abnormality of the light emitting element normally connected to the second driving circuit at least in the second mode. The bypass path connects the first driving circuit to the second driving circuit. The switching portion is disposed in the bypass path so as to make the bypass path into a conductive state when an abnormality is detected, and to make the bypass path into a cutoff state when an abnormality is not detected.
