HEADLIGHT UPGRADES.....which?

I used aftermarket headlight assemblies and baked them open and used the reflector part of the housing to attach the lights. The sealed beam lights I used had four holes in the back and I ran ss screws from the back of the housing into the back of the housing of the sealed beam lights. I lined them up at 90 degrees to the bottom of the headlight housing. I also used 9007 female plugs to plug right into the factory plug in the truck. All in I think I had around $600 in the setup.
