Headlight Question

I am not into making up one of these harnesses through a kit, sounds to much like the painful, 'Painless' wiring kit to me. I have 3 of the Crackedback harnesses, they are pretty much plug and play. He is also a good guy to deal with, does what he says. His harnesses also do what they are supposed to do. No need for all of that led fancy stuff. How did we ever find our way around in the dark with good old regulator incandescent headlights? Then the now blinding led's headlights, now I can't see where the hell I'm going because of the blinding oncoming or following blinding light. Drove truck for 37 years, I have watched the transition, give me the old days back , I pretty much hate led's! Sorry for the rant, but it's true.
