    • The one to the LEFT of the Koito is the Stanley biled. Found on Mazda and Subaru.

      Here are two Stanley bileds. Dual chip VS Single Chip. Dual chip is only found on Toyota RAV4.

      • 2 days ago I get my 2019 mazda 3. So I was able to made some pics of the headlights and output shots:





        It's clear this are Koyto's. I only don't know what type? The output is fine, and they have a nice colors on the cutt off.

        • Your version Koito biled is a new version that is not the original or the 2.0. I call it 2.5 for now until I'm able to inspect the module to determine if its a close relative or distant cousin. Performance is reasonable but its not as good as the other two.

          • I'm still curious. I also think they use different ones in the mazda 3. Depending from the car level. I have the basic ones, without led drl's. The ones who have led drl also have separate high beam leds. Adaptive.

            • In the US, all Mazda 3 models with LED headlamps use the same version biled.

              In Europe and else where it most likely is different depending on model.

              • Ah ok. I think the bileds I have are the same then in the US. All the pics I ve seen from US models don't have led halo's? Led drl's. Or am I wrong?

                Edit: Yes I m wrong. You also have led drl over there. Higher spec cars.

                IIHS test of both versions:

                It seems their using different projectors because the results of the low beams are not the same...

                  For me its all about swivel motor for projector in higher trim. In some headlamps there are dummy plastic boxes holding projector straight in the place of swivel motor in higher trim.

                      The projector modules are the same in all headlamps despite the slight inner housing style variances.

                      The reason for different IIHS measurements between models is caused by beam aim. One was set about -0.3 degrees.

                      • Ok, thnx! Whats the reason the lenses of those have that kind of structure? I mean, if they use clear lensen, isn't it better?
