Glen C, I found the light. It's called a "Quiklite". It's yellow, with a prefocused penlight bulb, and a gray slide switch. The tail just plugs into the cigarette lighter in your car. A red LED lets you know it's charging. Unfortunately, it's not labeled as to where it's made, but I swear I remember it as being made in Austrailia. I was impressed with it when I bought it, and bought two more. By the time I did that, they had changed the look of it a little bit by streamlining the head, and making the switch a bit smaller. These are labelled as being made in Mexico.
They are handy little lights, and I suppose somewhere out there is a new version with better batteries and an LED instead of an incandescent bulb. Maybe if you look around in the automotive section of some older hardware stores, you might be able to find one. Good luck.
