A trailer light that only has 1 wire means that it grounds through its mounting hardware. The single wire is the power wire. The best surface to ground a light to is steel. If steel is not available in the area the light installs you can attach a ring terminal and wire to the grounding stud and attach the other end of the wire to the original ground wire from the old light.
