What kind of automotive instrument? 12 to 16 volts work, so many laptop power supplies will do if the current draw is under 5 amps. A spare power supply from a desktop computer puts out a good several amps which I often use. Some people may cry about that and say these switching supplies will not work that way, but I guess they never tried it. The output really isn't that bad. Car batteries also make wonderful power supplies too from what I hear.
