Use a wire brush to clean the battery terminals and the inside of the battery cables where they connect to the battery terminals. If that doesn't fix it, I suspect the problem is the negative connection from your battery to the car body/engine block. Follow the thick cable from the negative terminal of the battery to where it connects to engine block. Make sure you have a good clean metal to metal contact. Use an ohm meter to check to make sure this cable and connection is good. If the connection to the engine block is bad the hood light might still be able to work if it has a separate connection to the negative battery terminal.
