Hi everyone,

What are the strips of led for under a window sill? They hang down
from the sill laying flush with the fascia. I have seen some with a
semicircle pattern.
Are they there to keep the water out? There are still drip grooves on
the underside of the sills.
I am not sure but I think I have only ever seen them used on houses
with either featheredge board or tiles.
How does the led tie into the window sill?
Does it fit into a second groove behind the drip groove? Or does it
simply lie under the window sill? Maybe pinned to the brick
underneath?

Regards,

Rich
