Technologies are disclosed for contingency vehicular signaling. A first DC power source may be connected with one or more indicators. The first DC power source may be connected with a second DC power source, and/or a third DC power source, via a semiconductor. The first DC power source may be configured to receive a second DC current flow from the second DC power source, and/or a third DC current flow from the third DC power source. The semiconductor may be configured to block a first DC current flow from the first DC power source to the second DC power source, and/or the third DC power source. The first DC power source may be configured to provide the one or more indicators with the first DC current flow via the at least one electrical switch regardless of a magnitude of the second DC current flow, and/or the third DC current flow.

A method is provided for operating an illuminating device for a vehicle that features means of influencing light or a plurality of light sources for the targeted generation of pixels of a light distribution. In the event of failure of at least one pixel of the light distribution caused by a defect in one section of the means of influencing light or by malfunction of one of the light sources, at least one non-defective section of the means of influencing light or at least one non-malfunctioning light source is actuated in order to correct the light distribution. The at least one non-defective section of the means of influencing light or at least one of the non-malfunctioning light sources is actuated in such a way that at least one pixel of the light distribution adjacent to the at least one malfunctioning pixel is reduced in its brightness.

A power supply circuit for supplying power to an electric load of a vehicle includes a relay and a relay control circuit. The relay is configure to be turned on when enabling the supply of power to the electric load and configured to be turned off when interrupting the supply of power to the electric load. The relay control circuit is configured to turn on the relay when an ignition of the vehicle is on regardless of a state of an operation part that is to be operated by a driver to operate the electric load.

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 method for providing redundant safety recovery lighting to a motor vehicle which motor vehicle includes an Electronic Control Unit (ECU), the method includes the steps of: a) allowing the ECU to identify a failed external light from a plurality of external lights of the motor vehicle; b) providing a database within the ECU that matches at least some of the plurality of external lights of the motor vehicle with substitute auxiliary external lights that can be activated in place of a failed one of the plurality of external lights; and c) based on a failed external light identified in step a), activating an auxiliary light matched with the failed external light in the databased in step b).

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.

A system includes a first power net in a vehicle electrically coupled to a first control unit. The first control unit controls first lights included in a second light set when the first power net is operational. A second power net in the vehicle is electrically coupled to the second light set and a second control unit. The second control unit controls the first lights when the first power net includes a fault condition.
