Not a fan of these small characters for the destination number/character, IMO the service number should be the most prominent part of the destination as from what I've gathered its the main thing most customers look out for.

I wouldn't mind the shifting of the service number to the opposite side of the destination if it weren't for the fact that the old displays have the colour box to indicate the service number on the nearside meaning we currently have some buses with the service number on one side and others on the other side, for the sake of consistency I feel you should go for one or the other, admittedly the refurbs seem to be getting full white displays to contract these problems but even still there's still a fair few number with the old displays.

Personally I feel B should always be avoided in service numbers due to it closely resembling a number 8.

Presumably the next step is dropping service numbers altogether like trentbarton and Hornby is now adopting at Transdev too on some routes.

EDIT: another concern is the small characters for service number is similar size to the ultimate destination which concerns me having experienced a similar issue in the past with Arriva Durham depot with the 7/7A both terminating at the Arnison Centre with the service number on the drivers side and I honestly struggled to distinguish as to whether it was a 7 or 7A as if it was the 7, the A in Arnison Centre was the same size as the 7 with no adequate spacing, so it looked more like it was operating the 7A as opposed to the 7
