A new family moved in a few houses down about a month ago. Shortly after, I noticed they changed their driveway lights to a red and a green bulb, like Christmas or something. As I mentioned, they just moved in, so that means they purposefully changed to those bulbs. I couldn't imagine why. Driving through the neighborhood, I've noticed a couple other houses with red and green driveway lights. I'm wondering if there's some weird cult I've been missing out on.
