this sounds like a superb idea for a product, who wants to manufacture
and market it... :)

One novel thought occurs to me (also from watching too much Home Front)
- If=20
you are seriously considering using LED's, then have you thought of
using=20
fibre-optic as an alternative?

You could have a light source indoors, and then run either single or
bundles=20
of fibre to wherever you want a point of light. - I would guess that the

light level would be comparable to LED's? - you're obviously not going
to=20
get great illumination from either, so I'm guessing that it's more for=20
effect...

Then you wouldn't have to run any electrickery outside at all, and you
could=20
change the light colour at anytime by changing the light source...
Whereas=20
once you'd fitted LED's you'd be stuck with whatever colour they
were....
