Answer 1

I'm thinking along the lines of an old boat.  It is way to simple to be a car.  There is no sign of any engine circuitry just nautical looking lights so it could be marker lights for a sailing vessel.

Answer 3

It is the electrical system for an old boat. The battery, wiring harness, and light prove this.
