Turnout Indicator Diagram

Gary Yurgil

There is a wiring diagram called DCC TURNOUT DIRECTION INDICATOR SIGNALS USING 2-WIRE BI-COLOR LEDS.  I admit not being the sharpest tool in the box, but it looks to me like both phases of the AC come together in a point right before the LED.  Do the diodes prevent any kind on short?  I'm hesitant to try it before plugging the power in.

Gary the resistors prevent a rail to rail short.
