Application Examples.
The diagram shows how to wire day, night and tail lights to a 3-output decoder to give automatic directional lighting as well as parking lights (red both ends) using only F0 and F1 functions. Additionally adding an extra output and F2 will allow the lights to be switched off completely (or just the tail lights when hauling a train or running in multiple).

Diagram 2 shows how to connect both head and tail lights to a single output of a low output power decoder to give automatic directional lighting with F0 active, and parking lights when F0 is inactive.
Diagram 3 shows how to connect head and tail LEDs in inverse parallel between two outputs allowing the connection of all the directional lighting through the train with a two pole conductive coupling and allows the use of red/white or red/yellow bicolour LEDs.
This example is similar in function to the 170 example (without day/night headlight switching) using the same function allocations, but only uses one function decoder for the whole train. Since the 156 does not have lighting fitted as standard there are no pickups on the trailer car, so in this example a 2-pole conductive coupling is used to connect the trailer lighting to the power car. F0 switches between directional lighting (white at front and red at rear) and parking lighting (red both ends) F2 switches off the tail lights (8-output decoder and on the power car only).
