Anyone ever seen any of the garage-door-opener makers that
provide terminals so that one could attach an external indicator
light that would then light up any time the garage door was
open?

The old folks here in Florida are very frequently forgetting to close
their overhead garage doors and some of them (like me) have been
wondering how hard it might be to build an add-on circuit or whatever
so that an indicator light that we would install in their house would
remain on.

An electric indicator would suit people who
cannot put in the front yard a mirror that
reflects the front of the garage to the living
room window.
