    What do the beams look like when you install name brand (Osram/Philips) halogen H7 bulbs? Does the beam pattern improve?

    If the answer is YES, then the problem is the HID bulbs. They are either not seated correctly or poorly constructed/designed.

    If the answer is NO, then the problem is the headlamps. They are poorly manufactured and have low quality/cheap projectors. Which is common for aftermarket headlamps.

            The problem is the shitty aftermarket headlight projectors.

            Do a retrofit with proper projectors in this or the OEM headlights, I would go for the OEM.

            Those CNLight HID bulbs are usually ok. They could have little misalignment (that shimming resolves it), but nothing like that.

              are you sure 100% that the problem is my aftermarket headlight projectors ?

              i would like to try other bulbs but i am not sure if it will be fine after the new ones.

              *i dont have time and money for other solution like retrofit right now.

              thanks again.

                Can you post pictures of one headlight on a wall at a time? It looks like one is way wacked up and the other might be OK. Also, got a link to where you bought the headlights from? They might not be trash, kind of look like some of the Chinese ones that used a decent projector like the Q5R.

                    Well I think never mind about it being a Q5R, those are bixenon and use a D2S bulb.

                        The second link shows the back of the housing open, where the bulb opening and spring mounting clip is in the picture. I see how they say it is H7 halogen, but can be "upgraded" to HID. So the "upgrade" is a rebased H7 HID.

                        evo77 suggested a check, where if you put OE H7 halogen bulbs, does the output still look poor or not. If it looks poor, then HID won't help. If good H7 halogen bulb generates good output, there's a chance that a rebased H7 HID can be ok. Although one should note that OE HID bulbs do not come in the halogen-standard H7 base. They are D1S, D2S, D3S, or D4S for projectors. The location of the HID arc relative to the base (and the rest of the projector optics) and the projector optics design determine the output quality.

                        Aftermarket headlights do not have to come with good projectors; many have terrible outputs but look "bright".

                          what is OE ?

                          if the OE H7 halogen will be good . then could i try the D2S ?

                          or only another bulbs rebased H7 HID ?

                              Replace projectors with HID projectors.

                              While you save up money and time, replace HID kit with halogen H7 bulbs.
