 Their 11/45 had lights, but ran RSTS most of the time. 
I'm confused by the "but".  11/45s have lights and switches panels, and RSTS
would display a nice lights pattern on that when idle.  Many versions could optionally do
a rather amazing lights pattern involving both the address and the data lights
("fancy nuljob").
