A retrofit will get you there. Many people up here in AK drive with light bars, but they are incredibly blinding. We don't have many rural roads, because well, we don't have many roads. It may be possible to find DOT approved aux lights though that have a good cut offGoing to be pretty tough to get 1980's technology headlights to be brighter than modern lightbars. In Alaska I have to imagine the population and road density are low enough you could just wire a light bar to your high beams?? I know my two 10" Rigid light bars are much brighter than my high beams.
