As for the DD SS3 fogs, the Pro is a good choice, but be careful. It has more power than the Sport, but less than the Max, More importantly though, the horizontal beam is not as well controlled as the Sport or Max.

What does that mean? The beam pattern is taller and thus there is more up light - which an bother oncoming drivers. Even with proper aiming, the Pro is kind of tough to run on the street where the Sport and surprisingly the Max - with proper aiming - work quite well. I know because I went from the Pro to the Max.
