The headlight lens does indeed make a difference. I had one lens off and another one on and there's a difference between the light output and colors shown. Sanding and polishing won't be as effective as new lenses because the lens gets internally yellowed
I have a facelift coupe so i cant just purchase lens.
Here is a pic of both lights where u can see the light mark on the lens. But on the driver side its there slightly with the xenon off. Hard to see but its there on the driver side and not passenger side which has better output.
