We use to do this quite often in the Automotive world. Put the head light in series with the battery cable and the Battery post. When you had a harness short or some such and needed to have a good resistance to take some of the load while you looked for the issue. Pulling each circuit fuse until the light went out would identify the short or draw. Then a methodical harness wiggle or device disconnect on that particular circuit. Could take time but sometimes the smoke would let you now exactly where Later in the business we had better tools, Thermal Imagers, Power probes, etc, So this old reliable way stayed on the shelf. Parasitic draw is a major issue in the New Automotive world.In addition to the above, and I mentioned reacquainting myself to a multimeter in a range I don't normally use, this Wagner Halogen Headlamp (or something like it) can be a good was to check and test to be sure you are in the right range-
