1982 308 GTSi Low Fuel Warning light

Is there any way to check the "Low Fuel Warning" light (amber in color) before I take the instrument panel out to check the blub? I believe that it uses the fuel quantity mechanism in the fuel tank. At least the wire (red and black) is connected at that area.

Thanks in advance.

you can pull the fuel sender unit up and out and replug the wires to insure the float is going all the way to the bottom.
