No EDS is infalliable... LED-based EDS is generally less
reliable than its predecessors.

This was the first LECIP EDS on a CDGE B9TL bus, and it was
corrupted shortly. If malfunctions were the only factor,
SBS Transit would have gotten something else long ago...

I am not defending any particular brand. My point here is that
there are multiple criteria to consider in tenders and
procurements, and it is too easy to oversimplify matters.
Inventory can be purchased in separate batches. It does not
necessarily need to match with the number of new buses
purchased.
Only time will tell how long these equipment will last. Transit
Media was frequently praised when it was first introduced, and look
how long it lasted.
I will stop this debate here.
The failure rate for Hanover has been pretty low since its
introduction. No EDS is invincible.
besides, unless you happen to be aware of any information that is
employee only....
