DTX LED

I noticed the new orange LED signs at DTX today.
Other than the size and color, are they any different than the old red signs?
That is, are they actually going to tell us anything other than not to smoke?
How much more money can the T waste on stuff like this?
Whose brother works for the sign company?
In case you're not in the know, the T has had LED signs for years in many stations. I can imagine that they cost a good amount, even if the T goes with the lowest bidder.
The thing is that these signs have done NOTHING. EVER.
All they've told is not to smoke and to visit mbta.com.
They are almost as bad as the "announcements" the T makes telling us to hold on to the handrail on escalators.
