The current view from our living room window - we got the lights up just in time for the snow. You'll also notice in the lower right corner of the frame, however, that while I tested them RIGHT before we wound them in and out of each and every (OK, every other) railing rung, half the bulbs decided to stay quiet.
I will say this: presumably out of respect for my mildly compulsive self, they chose a junction (stairs to deck) at which to make the transition from off to on. Or they suspected that if they'd been lit, say, halfway up the stairs, I'd have likely ripped the lot of them out and called the whole thing off.
I have to say, I do like how they glow from inside their snowcases.
