Forget retrofitting EDS into older buses, it's not worth the
hassle. Anyway, they will be too small, making
them pointless.
I honestly feel that the old plastic signs are better. There was
a very good reason SBS held onto plastic destos on production
fleets all the way up till 2006 with the CDGE B9TLs. It's cheap,
nearly failsafe and legible.
However, it would be nice if the destos were white-on-black or
yellow-on-black, would be more readable.
