We have the same NHTSA headlights, I think that are also used on Freightliner truck.
It is terrible driving at night. We have had to stop and use a flashlight to read road signs. I have to get out and direct her to park at night, the lights re so bad.
It is a common problem, I'm having heavier wiring run and a relay installed before next time out. The driving lights are large but no better than a kerosene lamp. Maybe we can find better units that will fit. I can see no solution to replacing the head light assembly, as they are peculiar in style and nothing else will fit. The problem is the little reflector inside, to prevent direct light out the front. All you get is reflected, poorly diffused light out the lens. If I had the money, I would have the cap redone with holes to fit old round four light setup. That would give excellent light, I thing, better than our little AMG perhaps. s it is now 50 ft down the road is about it, and forget reading signs or seeing someone cross the road.
