There is a red streetlite currently at Gateshead Interchange. A good chance to see it in action.
Edit: My uncle, who is a bus driver for GNE, noticed it earlier and e-mailed me and my friend, 'NorthEastBuses' has just sent me a photo of it displaying '123 Go North East' on the destination display, obviously out of service, but I believe it has since left the interchange.
