There is an older Hella aux. light called the XL. if I remember correctly. This rectangular light for under or over bumper mounting was based on the 5 series. There were 3 versions - a driving light for long range, a fog light lens in white or yellow, and the XL which had a clear lens designed specifically to be an auxilary headlight to assist the often mediocre US headlights of the time. Hella stopped making them 10? years ago as they just didn't sell, but I bought a new set on e-bay for $70?, and haven't put it on anything yet. I think people here just didn't understand what a non fog, non driving, extra headlight was for, and in Europe people already had better headlights. Again, they are supposed to reinforce the low beam - no high beam - headlight and are still around. Pep boys, among others, used to sell them. A little patience or junkyard / craigs list /e-bay might scare one up. Just FYI.

AND OF COURSE A RELAY SETUP WILL HELP THE PLASTIC W/9004 BULBS UNIT RUN AS BRIGHTLY AS POSSIBLE (MAYBE putco WAREHOUSE?). Cleaning the plastic lens, or new lenses from e-bay - were $25 delivered, and new standard 9004 bulbs (I don't think there is a Phillips XTREME in 9004)will all make positive but modest incremental changes at modest cost.
