Led Headight Question

There you go again with the "facts" slantsixdan.

You are 100% true but do you always have to be so right? Now as for the headlights by JW Speaker; do you have to buy those lamp adjuster assemblies like Amazon recommends?
I'm worried about the lights pushing to far forward in my 66' Barracuda if I use them. I cannot find (and I only quickly looked) any dimensions on the bulbs let along a rear picture of the bulbs.
I too want a really good set of lamps for the front but everything is sub-par. Even the Trucklite units ( I installed for a client) were so/so. At night the difference between high and low beam seemed very little. I worry about oncoming traffic on a dark night. They did have a very "military" feel when installed in his truck. Looks I give a 9, working I give a 6.5.
