Hi Howard...

How about doing away with it (the light, not the opener)
and replacing it instead for a very few dollars with
something (imho) far better ?

Consider installing one of those yard "security" lights,
that turn on when anyone/anything approaches, and remain on
for a few minutes?

Advantages - it can be mounted anywhere in your garage,
far better than dead center over the car roof. It will
come on if you open the walk in door after dark. Some, if
not all, can accept two reflector bulbs, lighting far
better. It can be forced on to provide regular lighting,
ie working on the car or whatever. It provides a tiny
bit of security - maybe a deterent if someone should
snoop around or try to get into your garage (even more
valuable if you have an attached garage) And they cost
incredibly little - I've seen them on sale for as little
as 5 bucks (canadian)

Just for your consideration.

Take care.

Ken

What about using one of those cheap timers used to keep a bathroom extractor
fan running for a few minutes after the light is switched off?

I'm not sure I've even seen something dedicated to that. Are those
wind up timer switches on a lightswitch panel?

No, its an electronic add-on to a bathroom extractor

Light turned on = fan starts running
Light turned off = fan continues running for a per-determined period then
shuts off

There's lots of circuits out there, I'd probably use a 555, optoisolator and
a triac with the handful of resistors and capacitors to glue it all
together.

Old toasters are cheap at tresale shops, you could uise the nichrome
wire from them, put two or more in parallel if they get too hot when
the moptor is running.
