The lenses are cut that way to one keep the cut off low enough to not blind oncoming traffic and two, it flares up to the passenger side to better illuminate signs, exits and such.
My cebie's are the same way, I thought of ordering one European one for the drivers side to see if there was a benefit but never got around to it. And yes anything is better than stock, I can't tell you how many times I got stopped and told to turn my headlights on. I always ran with the fogs since they were better.
Good to know, thanks dude. It makes sense.
My fogs cover the little dark spot below the headlights just right. It would aggravate me if I didn't have my fogs.
