I've had these "Ingress Protection Factor" IPF 968's since '06. They're about the same as the rectangular 868's. Hybrid reflector is a good theory, but they don't throw any farther than my HIR bulb high beams. I've tested them during a completely dark sky night.I like those... a lot. It does look pretty "period correct" as you mentioned. Do you mind posting up a little review on 'em or making a few more pics? I'd like to hear your comments on the "hybrid" reflector in there. Does it throw a good far light? How about the side to side movement? Is it a noticeable difference above and beyond what the low/high beams put out?
Just a little wider coverage up close. I have yellow halogens bulbs in now for snow and fog. Costco had the 968's for around $90 years ago. I got mine from the outfitter that sold me the ARB bumper. Oh, and, they look period correct.
