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.

Abstract: Vehicle indicator lights, such as run-brake lights and/or side running lights, are converted to run-turn-brake indicator lights. A run-turn-brake converter is connected to vehicle-supplied run, brake, left turn, and right turn signal leads, the run-turn-brake converter producing left and right run-turn-brake signals. Existing vehicle wiring is reconfigured by disconnecting a first lead wire from the low-intensity input of a first three-terminal brake-run light socket, disconnecting a second lead wire from the low-intensity input terminal of a second three-terminal brake-run light socket, disconnecting a third lead wire from the high-intensity input terminal of the second three-terminal brake-run light socket, and connecting the second lead wire to the high-intensity input terminal of the second three-terminal brake-run light socket. The left and right run-turn-brake signals are connected to the sockets via the second lead wire and via a fourth lead wire, respectively.
