I have seen the LMC ones, I think that they are better than the sealed beam ones. My buddy then put LED bulbs on them which he said helped, but of course the pattern wasn't as good.
He changed the core support to use the 5x7 JW speaker lights.
I have the old Bosch E code housings in all 4 positions in my '90. I like them a lot, but they aren't perfect. I think that there may still be some on ebay. I got mine from an old member on here, before he sold off what he had. If you stick with halogen, I would check to see If you need to do a relay system to keep the voltage up.
Have you looked at the SAE compliant ones that Rigid has for auxiliary lighting? You could possibly run those to help out the headlights on the road, you would have to adjust properly. Maybe check your laws ??
