Matrix Headlights Alignment

[UnsungZero_OldTimeAdMan]

Why do we have to follow eu code standard!!! I have the same issue.. I can’t see left side.

Because US code is, without EU influence is even worse. Without it, we wouldn't even have gen 2's matrix lights. And the lights don't kick up to the left, like the right side, because you don't want to blind oncoming drivers and—since we drive on the right side on this continent—all of the signs you need to see are on the right side. If you can't see the left side of the road at all then something is wrong with your headlights or vision.

I see this lame, facile idea bandied about all the time and it irritates me every time. US and EU vehicle standards are generally harmonized and have been for decades. Innovation flows in both directions.

The key difference is not in the implementation of a given feature, but how it's defined and tested. To oversimplify, in the EU each new vehicle model is tested by a certification body for compliance with their regulations. This allows for some subjectivity in the testing. If the testers decide that a given set of headlights didn't blind them while testing, then it is a approved and the vehicle is certified as road legal.

In the US, testing procedures and required results are written into the regulations. If the manufacturer self-tests the feature according to the specified procedure and gets an acceptable result, the vehicle is road legal. There is no subjectivity in this system - these standards must be be objective and quantifiable so they can be written into the regulations.

You can see the challenge with matrix headlights given how they operate. The delay in adoption in the US was driven almost entirely by the challenge of creating a test procedure and standards for a system that changes in operation.

Each approach has pros and cons and one is not inherently superior to the other.

Tell you what, I'll do that when you stat thinking, or stop being a jerk. Either way I doubt I'll need to start my company any time soon.
