What Paladin said -click on link to our History page for the story on the Ford Flat Rock Lamp Factory. CM HALL LAMP CO: DETROIT, MI. was the only FORD approved US vendor to supply light kits to their vehicles (Canada used their own supplier). The FORD Flat Rock factory suppplied much of the lighting kits, but tractors inlcuded the implement lamp after 1949 and both FORD and Hall supplied them as well. Tract-O-Lite was a FORD trademark. The tractor worklights were identical ( I have a copy of the original drawing) except the Hall made worklights had their logo stamped by the light switch. Ford had no stampings but the lamp itself had the FORD script logo. Additionally though, the CM HALL logo was changed to simply "HALL" on lights after 1947 supplied exclusively to Ferguson TO tractors. They were different than the Tract-O-Lites in their design in that they had two bezel screws 180 degrees apart and "HALL" was stamped near the mounting plate. The design in the mounting of the sealed beam lamp was different, actually better in my opinion, because they used two flat plates to hold the lamp in place. So if you are asking if the later Ferguson HALL lamps are the same as the early CM HALL lamps, no, not the same, but still made by HALL. HTH...
