It sounds like you need some original headlights! The originals were made by the Guide Company, and had a hollow, threaded tube on the side of the light that went through the hole in the hood and grille, which the wire came through, and the fastening nut screwed on from under the hood on the inside. You can find repros or originals at tractor shows. If the tractor has been converted to 12v, you can take the 6v bulbs out and install 12v fog light bulbs of around 110 candlepower. They shine as bright as sealed beams. Hope this helps.
