Abstract: An apparatus includes a light-emitting diode (LED) driver circuit, one or more LEDs of an LED array, and an electronic switching circuit. The LED driver circuit is configured to generate an electric current. The one or more LEDs are electrically connected to the LED driver circuit. The electronic switching circuit is electrically connected to the one or more LEDs and configured to be placed in one of multiple switching configurations. The electronic switching circuit is further configured to direct a portion of the electric current away from the one or more LEDs, such that a remaining portion of the electric current drives the one or more LEDs. The portion of the electric current corresponds to the one of the multiple switching configurations.

Abstract: A programmable turn signal and hazard flasher control system (10, 100) includes a lamp control module (12, 108) coupling a turn signal request unit (14, 106) to a number of turn signal lamps (20-30). The module (12, 108) couples the turn signal request unit (14, 106) to a number of vehicle turn signal lamps (20-26) in a first mode of operation and to a number of vehicle turn signal lamps (20-26) as well as a number of additional turn signal lamps (28, 30) in a second mode of operation to thereby accommodate lighting requirements of a trailer or other towed vehicle or to accommodate different lighting requirements in vehicles of a common vehicle platform. The load current to the turn signal lamps (20-30) in either case flows through a shunt resistor R1, and is controlled by a flasher circuit (54) during normal operation to a first flash rate and during a lamp failure condition to a second faster flash rate.
