What are the North American laws concerning headlights (color, brightness/depth) that you really should know?

In the U.S., all states call for that automobiles have headlights that meet up with specific standards. But only some aftermarket products fulfill these prerequisites. So try to remember that putting in lighting solutions diverse from the legal criteria can get you a ticket.

Light-weight Coloring

Every point out needs headlights to be white or amber. This coloring restriction also applies to roof lights, under-glow, and motor compartment lighting to stop confusion with crisis motor vehicles. We propose sticking with “DOT-approved” headlights.
