A light bar has a circuit board positioned within a housing and having a plurality of light emitting diodes (LEDs) or a thin-film-transistor liquid-crystal display (TFT LCD) is configured to transmit light. The housing has wiring electrically connected to a controller. The controller is configured to receive signals from the electrical system of the vehicle, interpret the signals received from the electrical system of the vehicle, and in response automatically control illumination of independently controllable segments of the vehicle light bar. The controller is initially programmed to perform specific function(s) and/or strobe according to specific patterns and is thereafter at least partially restricted from being reprogrammed by a user to serve other function(s), either by restricting the emission of light in at least one color and/or preventing specific strobing pattern(s).

A hazard beacon has an interface to a vehicle wiring harness configured to detect that vehicle emergency indicators have been deployed, a plurality of separately strobe capable light segments forming a hazard symbol, and a microcontroller controlling operation of the plurality of separately strobe capable light segments.

A safety accessory for mounting on a vehicle comprises a housing having a front side and a back side, and a laterally extending mounting portion for connecting to the vehicle, a mirror mounted on the front side, and a bulb assembly within the housing facing the back side. The bulb assembly comprises a plurality of white, amber and red light sources, and a control circuit connected between light sources and a plurality of inputs. The control circuit causes the white light sources to be on when power is received at a first input, the amber light sources to flash in a standard flash pattern when power is received at a second input, the red light sources to flash in the standard pattern when power is received at a third input, and the amber light sources to flash in an emergency strobe pattern when power is received at a fourth input.

The present invention is directed to a compact light-emitting diode arrangement which can be used generically but, by reason of the compact design, is advantageous in particular for use in a vehicle. For instance, the compact light-emitting diode arrangement can be used e.g. as interior lighting in a car. The present invention is also directed to a vehicle component having the compact light-emitting diode arrangement. Furthermore, a method for producing the compact light-emitting diode arrangement is proposed as is a computer program product including control commands which implement the proposed method.

A system includes a first lead connecting to existing vehicle wiring for activating a signal light of a right side of a vehicle, and a first strobing light module having a first microcontroller connected to the first lead and operating a first light capable of strobing operation. A second lead connects to existing vehicle wiring for activating a signal light of a left side of the vehicle, and a second strobing light module having a second microcontroller connects to the second lead and operating a light capable of strobing operation. The first and second microcontrollers are communicatively coupled and each provides a signal to the other when it has detected activation of its respective lead. The first and second microcontrollers both strobe their respective light capable of strobing operation upon receiving the signal from the other and the signal from their own respective lead.

A system includes a microcontroller that controls illumination of a plurality of vehicle lights that are operable in a flashing state wherein the plurality of lights operate as hazard flashers visible on a front and rear of a vehicle and a strobing state wherein the plurality of lights operate as strobing lights visible on the front and rear of the vehicle. The system includes a strobe activation switch that provides a signal to the microcontroller to operate the plurality of vehicle lights in the second strobing state. The microcontroller operates the plurality of vehicle lights in the first hazard flasher state in response activation of an existing hazard flasher switch. The strobing state has a flash rate that is perceptibly faster than a flash rate of the flashing state.
