If you go visiting other van dwellers during longer winter nights, you might have trouble finding where you parked your van—especially if the visit included some adult beverages. A flashlight is good if you know the direction you need to head. Otherwise, a light on the van can be handy. A porch light, if you will. "Ah, there I am, over there."
So, I got this solar powered yard light. It comes on automatically when it's dark. The light pivots in the "rock." There's a switch to choose between warm-ish or cool-ish light. Pointed at the van, the vehicle becomes a shining beacon in the night welcoming home the weary—assuming I'm coming from a direction where I can see the lighted side. Hmmm, maybe I need one for the other side.
