I wouldn't imagine Hanover would sell rear destination displays in white if it would raise issues for the bus companies?
Although the ones First Eastern Counties use on their Enviro400s allocated to service X1 may not be provided by Hanover (someone may be able to confirm this one, as I'm not sure), they have rear white destination displays and I'd imagine if GNE go for white as standard in this year's orders, they'll go for white all-around.

The issue is, that it is an offence under law to show Red light on the front of a vehicle and White light (unless reversing) on the rear.
