So I went ahead and bought these replica HID/LED headlights from ebay. They are also available to alibaba.oom
At first I was skeptical on ordering them because they were coming from china, and it did not seem like many of them were sold. I did some research on them, and they are actually made of good quality materials.
The clear headlight lens is made out of PC plastic, which is the kind of plastic that OEM uses, the projector is a Bosch 2nd generation projector, which by the way have excellent light output and a cutoff. The HID kit which comes with these headlights is a Phillips HID kit, which is pretty nice.
The fitment of these headlights is not 100%, but it is VERY close to being an exact fitment. The only spot which they do not fit with 100% is by the fender, and it is not noticeable at all. 99% fitment.
The only issue I had with these headlights is that one of them would not adjust, but that was my fault because I turned the adjustor too far, and it came out of the socket, which was easy to put back in. All you have to do to put it back in if it happens is take off the cap on the back of the headlight, and pull the plastic back of the projector onto a white ball looking leveler. Just connect those two back together and it will work again.
As for the error codes, on the GLI I get bulb out error for the left and front side light, other than that, I do not get any errors. But it might be different on the regular Jetta. You will need to use VAG-COM in order to enable HID headlights with Bi-xenon, and also to enable xenon with shutter in order for them to work properly.
The seller always kept good communication throughout the process, and would always tell me the status of the shipment. It did take a little while for them to get here but that is only because they were back-ordered, but once they shipped, I received them in only 4 days.
The LEDs are pretty bright, obviously not as bright as the OEM headlights, but they are bright enough to where you can see them during the day, and they are pretty bright at night. The projector in these headlights is awesome, and the light output is great with a very clean cut off. The LEDs function as the city lights, and they do stay on when the HIDs are on. The only difference between these headlights and the OEM ones is that there is no orange reflector in them, but it is instead smoked, and also the bottom part of the projector housing is flattened instead of round. The color temperature of the HIDs is 5000K which is extremely white, it looks like day light!
Overall, I would highly recommend these headlights if you are looking for an OEM look headlight without the OEM price. They are worth the price to pay, and they look great.
Here are a few pictures with just the LEDs on.
