Abstract: A control system for a turn/brake light of a vehicle, includes a control circuit configured to receive a plurality of analog voltage inputs and to deliver an analog voltage output based at least upon the plurality of inputs. A light emitter is connected to the control circuit. The light emitter includes at least one dual-color LED configured to be selectively illuminated based on the analog voltage output. The control circuit can receive a turn/brake signal and produce at least a first output voltage and a second output voltage. The dual-color LED produces a first color output in response to the first output voltage level and a second color output in response to the second output voltage level.

Abstract: A control circuit is provided for controlling the warning lights on a vehicle having first and second composite brake/turn lights. The control circuit receives two composite input signals from the vehicle generated by operation of the vehicle's brake and turn signal controls. The control circuit jointly processes the composite input signals to separate the brake and turn indications in order to determine the operational state of the vehicle and generates composite output signals to control the composite brake/turn signals. In one embodiment, a braking pattern is applied to both composite brake/turn signals when the vehicle is braking only. When the vehicle is braking and turning simultaneously, a turn signal pattern is applied to one of the composite brake/turn lights and the other composite brake/turn light is turned on without modulation.

Abstract: A control circuit for operating the lights of a vehicle. In one embodiment, the rear lights of the vehicle are controlled by the control circuit. The control circuit illuminates two or more of the vehicle lights in a common pattern to indicate a specific vehicle operation. When the vehicle simultaneously performs two operations, the controller may transition the lights to illuminate in different patterns to clearly indicate the separate vehicle operations. The controller may further provide for adjusting the light intensity of one or more of the lights. The lights may be adjusted to have a similar intensity to prevent confusion when the different lights are used in combination to indicate a vehicle operation.

Abstract: An electronic control circuit controls a vehicle's lamp to selectively operate as a turning signal, emergency signal, or vehicle running lamp. Notably, the circuit permits the lamp to operate as an emergency signal lamp even when the vehicle is off. The circuit includes a supply circuit, a control circuit, and a disrupt circuit. The supply circuit supplies voltage to the lamp if either or both of a vehicle running signal and a flash signal have a first input value. Meanwhile, the control circuit generates a control signal having a first control value if the vehicle running signal and the flash signal have different values, and a second control value if the signals have the same value. The disrupt circuit then connects the lamp to ground if the control signal has the first control value, but disrupts that connection if the control signal has the second control value.
