Thought I'd pass this on after reading Trader's post about his wired lights.
A few months ago I installed 4 of these lights:

Didn't really think it through, because I've got 18" eaves that would block the solar
collectors from the sunlight. I had to hang them on the gutters. Too late to return them,
and I didn't want to throw away 80 bucks. After looking around in vain for some kind of
connector that would attach them to the gutter, I came up with this idea.
I cut 4 8" pieces of 3" PVC pipe, then cut a lengthwise slit in each one. Used an angle
grinder with a cuttoff disk. My son went on the ladder and somehow spread the pipe and got
it past the formed gutter lip. He was cussing. I noted the position of the slit - about
7:30 o'clock when looking from the left. Then I screwed the base of the lights on the
pipes at 3 o'clock using the wall plugs that came with them. I tried cutting some wedges
to spread the pipes but gave that up, and used 3" C-clamps to pry them open instead.
He didn't have any problems putting them on. You can slide the pipes until you hit a
gutter hanger, making for some adjustability. They don't look elegant, but they work.
