Well the way the cut off is on them, it's notched out on the left side so if you were driving down the road it would blind everyone in the opposite lane. Now if you were in a place where they drove on the opposite side of the road, then you wouldn't blind anyone since it would be lighting up the side of the road more. You don't have to do it, but it's more of a respect thing.

Thank you so much for the clean up,. so if japan were ordering headlights from us, they would be doing the same to our headlights..hmm interesting. i always thought headlights were centered... uurrgh that conversion takes alot of patience..Thanks mkernz22

If you park a car in front of a wall, you'll see that one side of your headlights is lower than the other, so you don't blind incoming traffic on the other lane. So i believe that conversion is necessary to ensure safety of everyone on the road. Some countries (or states in your case) even check this on the annual car inspection.

Here is a dutch tutorial on how to do the conversion:

Should't be a problem to understand it using google trahslator. Hope it helps

That wouldn't be the case for them because we never got projectors here in the US, just the regular frosted ones or whatever you call them. The ones that cone stock here are centered, its only the projectors that aren't centered.

If you live in the states then the conversion would be mandatory. There's lazy people like me who just drives it without the conversion. Either way the lights are still illegal to drive on the streets. Lol.

The problem is that shaped beam patterns were not legal in the U.S. until a few years ago. The U.S. preferred to keep headlights acting as if it were still the 1950s, with two hotspots on the road and half the light scattered upwards to illuminate overhead signs.

Europe and the rest of the developed world used the sharp horizontal cutoff to produce an even spread of light on the road -- overhead signs less than 40 years old are almost all self-lit -- with the beam spreading upward towards one end to illuminate roadside signs. Japan and the UK, as well as a few smaller Commonwealth countries, have that kink on the opposite side to pretty much the rest of the world. Canada compromised -- we'd accept both ECE beam patterns and the ancient US DOT (Department of Transportation) beam patterns.

THUS, I'd HIGHLY recommend having fog lights installed to illuminate over head reflective signs on freeways and highways.
