You don't need to move bulbs around, power them, and blow more fuses. A meter will diagnose where the short is located. With light circuit NOT POWERED (pull fuse), Put one lead on the (+) wire from the distribution center that feeds the light circuit and the other lead to known good (-)ground. Check for continuity. You should have continuity if there is a short in the circuit. Remove (+) from closest light fixture and observe for continuity. If you have continuity, the short is between distribution and that fixture. If not, the short is downstream from that fixture.
