    Got two headlights today. Ripped apart and tested projectors. Lenses are not very round. Forgot to take pics. But it has wierd light dip near center cutoff. I can see why and it's on purpose and I see how it can be fixed. Deff designed that way

      That is designed on purpose. It is present in every OEM LED projector. It falls on a US regulated test point that is supposed to control glare just below the horizontal plane. The Japanese and Korean light manufacturers usually engineer a "nib" on the shield to shade that area. The European light manufacturers usually create a lowered step around that area.

        I want to remove that nib. Hid projectors didn't seem to have that

          HID projectors don't have it because HID lamps are usually designed as a VOL type lamp, which means the visual aiming is set on the LEFT side. And for US regulations that means that the cutoff needs to rest 0.4 degrees down.

          The test point in question is at 0.86 degrees down.

          LED headlamps are usually designed a VOR type lamp, which means the visual aiming is set on the RIGHT side. And VOR lamps typically have a straight beam (yes some have a small step) but it rests right up on the horizontal plane. This means there is more light illuminating closer to the cutoff on the left side than a HID projector. Which is why a VOR lamp has that glare test point shaded.

          See below image for comparison of both VOL and VOR beams and how they fall over the lower glare test point.

            Oh ok. I guess I'll leave it then. Need to figure out if I Wana mess with lens or not since it's not regular shape. Ordered one driver side headlight for 50shipped. They are pretty cheap
