LCRX with Bicolor LED  Markers

RailSounds Control Connections
This circuit shows how to use bicolored LEDs for changable marker lamp applications. This circuit uses the cab lamp to pull current off the LCRX output.

This circuit takes advantage of the DC offset present at the outputs in command mode.

AUX-2 will turn on the cab lamp and allow you to control the color of the LED with the AUX-1, 8, 9, and 0 buttons. Playing with these functions will give you different combinations of flasher on/off, marker red/green.

The L, M, and H buttons on the CAB-1 will also change the color of the LED markers.
