Put a BLUE Light electric candle in your window this month!
Really?
That’s interesting…
That was my first thought - for soldiers.
Wasn’t there something about a light in the window during W.W.1? I;m just going by very vague memory here.
I just moved to the “other end” of my neighborhood and it turns out that this is the end that likes to decorate their houses for Christmas. I have no intentions of decorating but the lack of multi-colored lights amongst the sea of sparklies makes my house look awful creepy.
So, i did the best I could. I found 8 plastic battery-powered candles in my mom’s attic, bought 16 AA batteries and set them up in my 3 windows.
I broke 2 of them on setup, so each bedroom window has a single candle and the front window has 4. Of course, on the first night I forgot to turn off the bedroom window candles so I had 2 single candles that night. The second night I only managed to turn on the 4 large window candles. Tonight I left the house in a hurry and forgot to turn them on, and when I got home I noted that no one else’s lights were on so I had missed whatever standard timeframe for house lighting for the day.
Funny thing is - taking stock of the situation and driving by my awkwardly-lit house amongst the sea of lights, I wondered straight off if my neighbors might think I was Jewish.
I guess they do 
There’s also this story of a single candle in a window from the song ‘Morning Glory’ by Tim Buckley. First verse is below:
I lit my purest candle close to my
Window, hoping it would catch the eye
Of any vagabond who passed it by,
And I waited in my fleeting house
I don’t have an answer for you, but an observation. I have intended to post just such a question before.
My wifes parents moved from Canada to south-eastern Indiana and, when visiting, we have noticed at all times of the year that many houses display a single candle in one, many or all front windows. It does not appear to be a Christmas or Jewish tradition.
It does appear to have spawned an industry though.
When I was a kid (born in 1949,) my folks explained that it was “so the Christ Child could find his way to your house.” Later on, my town had a lot of folks setting out luminarios to line the driveway on Christmas Eve. Each luminario was a small paper bag with the top folded in a cuff. Inside was a handful of sand for weight and a plumber’s candle. Those who still do that now use plastic milk jugs instead of bags.
Even as a kid, I thought the idea of a baby wandering around in the snow was pretty silly.
