FUEL GAUGE SIGNAL

My yard neighbor kept lying down because he overlooked that his fuel reserves were running out.
So I went to him and changed the bulb on the fuel gauge. Now he notices again when he has to refuel and I don't have to keep towing him.
He missed the fuel gauge signal from previous versions ...
This script uses a visual sign on the fuel gauge to prompt you to refuel before the fuel tank is empty. (<10%)
