Does the light come on when the ignition is in the run position? If not, then you have a burnt out bulb. If it does come on, then you have a bad/disconnected switch at the emergency brake lever, or a loose wire.
Check carefuuly at the emerg actuator itself. You should see the switch built right on to it. The plug on it should have power to it. When you depress the pedal, the switch completes the circut to gound, if not working, you can check for power at switch connection plug, if you do, apply a grounded wire to the plug. If it lights .............It's an old truck, check your circut carefully
