Here we will explain how to realize a Ditchlight.
A Ditchlight are 2 lights of the front light, which blink alternately when operating bell / horn.
Here the circuit for a Ditchlight.


The values of the resistors have to be adjusted.

The following CVs have to be programmed using a XLS and when triggering the Ditchlights should take place on key 1:
CV 113=1 (A3 at Key 1)
CV 115=1 (A4 at Key 1)
CV 114=4 (Alternate blinking at A3)
CV 116=16 (inverse coupling at A3)
