4.15.3 Running light
An automatic running light can be created by slightly modifying the shift
register circuit.
One relay is always switched on. It starts at Q1, runs through to Q4 and then
starts again at Q1.
The marker relays for storage locations M1 to M4 are replaced by relays Q1
to Q4.
The shift pulse I1 has been automated by the flasher relay T1. The cycle
pulse M8 remains as it is.
On the first pass, the value is switched on once by N/C contact M9. If Q1 is
set, M9 is switched on. Once Q4 (the last storage location) has been
switched on, the value is passed back to Q1.
Try changing the times.
