I somehow managed not to see that one, today, despite a trip to Sunderland with part of the journey back on the 23, as I stopped off at my Mother in Law's on the way home.
I do prefer those to the orange displays - they show up a lot better in poor conditions. They go well with the lights on the streetlites, too and they're so distinctive and bright that you can tell the bus is coming from a long way off, even in heavy fog.
