Hi all.
Today I've sorted out the headlight washers on one of my preface Signums after the previous owner destroyed the passenger side nozzle running into a wall.

The one that I've fixed is a factory fit system and behaves totally different to to the one on my other Signum which is a retrofit (albeit using genuine parts from a donor).

I have one system that pulses about 0.5 second after the windscreen washer for about 1 second and another system that pulses about 1 second after the windscreen washer but does 2x 0.5 second pulses.

I never knew there was a variation..... who has what?
