Not to hijack the original thread but IMHO design is now playing a huge part. I drive 121 miles one way leaving at 4:45 am. This time of the year I am driving in the dark pretty much both ways. Combination of highway and back roads. The new super duties with their C shaped stacked headlight on low kill me! I run into enough of them that it is not aftermarket / modified / hi beams. I have my own opinion on modified headlights. I give kudos to Brian for trying to make them as legal as possible. I run into enough non DOT approved lights on my commute it is not even funny.
