The standard light pattern of a right-hand drive car shines up on the left to give a better view of the roadside and traffic signs. When this is driven in countries where they are driving on the right side of the road, oncoming traffic will be blinded. That is why this upward-looking part of the light pattern must be removed or mirrored to the other side. See the illustrations below for a clearer explanation.
Over time, the plastic that makes up your headlights will degrade and cloud over. Headlights are the most important things to keep clean on your car. Not only do these powerful beams let you see the road, they let other motorists seeyou. Most headlight lenses are made of polycarbonate plastic. This strong plastic is perfect for taking on harsh road conditions without breaking, which you definitely want, but it doesn’t play well with the sun. To protect it initially, manufacturers coat the lenses with a UV protective film. But over time this film is destroyed by UV rays, allowing the plastic to oxidize. If your headlights have started to haze over or become yellowish, then it’s clear the oxidation process hasbegun. I can restore these headlights, by sanding them and providing them with a new layer of coating. Making them like new again. Feel free to ask for the possibilities.
