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.
