RE lights typically don't last very long around here).

A few half-baked thoughts come to mind. A others have indicated,
motion detectors can be activated with false triggers such as animals,
debris blowing by, and even shrubbery/tree branches blowing in the
breeze. If a motion detector would work, you could put a socket
adapter in where the bulb normally goes, plug in an extension cord to
an X-10-type device which uses a 120v input. The X-10 would then
'trip' the house alarm.

Another option would be to use a door/window sensor on the door frame
-- perhaps several in series to arm for various break-in methods.

Not sure how to take care of the salt spray corrosion problem -- may
just have to replace the sensor devices annually?

Strung at various heights. Works good. You can tie one end to a metal
garbage can for effect. Or a stack of something.
