Not sure who asked the first question (wasn't Bill), but...

>>Aren't tower lights supposed to be on 24/7?

No, at least not if red lights (either steady or blinking) are used.
They have to be turned on only at "civil twilight time".  For the WMBR
tower on the Eastgate building, we have a light meter that does the job
for us.

I don't know why it is, but every strobe-lit tower I've ever seen has the
lights on 24/7.  Nor do I know what the criteria are for using strobes vs.
reds, but airport proximity can't be the only criteria.  Otherwise, all the
radio towers in or near downtown Boston would have to use strobes due to
Logan, and almost all of the downtown towers use red lights.
