Brite box a partial solution
I too have the Brite Box and it is at least a partial solution in that it lights up the area close in. But nothing short of an extra set of lights will throw a beam down the highway. IMHO, OEM headlights are designed to keep bright lights out of the eyes of oncoming drivers. That's fine, but OEMs don't light up dark highways far enough for some of us to see and avoid wildlife.
The problem is in the reflector design, which means brighter (and more costly) bulbs aren't worth the money.
