It's supposed to move around all over the place, same for cruise (only more frequent). WOT should have it somewhere in the rich region. Foot off accelerator, approaching a junction for instance, might well have no lights at all, until you either dip the clutch, or the revs fall below 1000 (ish) where the ICSV kicks in.

If you're not getting any of this activity, either your lambda's knackered, or you haven't wired it to the correct wire on the ECU...

 

On idle the lights flicker all over the place,mainly greens but occaisionally orange flickers too.On WOT all i get is a steady green (far right green) no other activity at all.

 

Sounds about right to me, I think the main thing is greens on WOT, and it'll be all over the place on idle, cold idle is usually all green on my one, then when it warms up idle is all over the shop.
