If you are talking about a light to pinpoint an airfield from a distance at night, what about an amber rotating or strobe light as used on construction sites on the various pieces of equipment and vehicles. For about $50 you can get one that plugs into your cigarette lighter in your car.
Many years ago I remember the Poms had (might still have) a flashing light at airfields that flashed the ID code in morse.
