I have already searched the forums and cannot find an answer to explain the difference between a projector / non-projector headlamp. I just installed a set of Hella/Xenon, with ballasts, etc. How do I know if these are projector headlamps? I want to purchase a new set of clear headlight lenses but I first need to figure out what these are. I switched out the stock Halogens for the xenons on my 99 540i. I switched over the headlight lenses on them prior to install so I didn't have to mess with reconditioning the other ones. :dunno:

My understanding is that projector low beams have a large "magnifying glass" lens, whereas non-projectors have diffused lenses. Most aftermarket halogens headlamps are projectors; I don't believe that HID has projection lenses, but rather have diffused lenses due to the concentrated brightness of the beam. If someone else understands this differently, please chime in....

HID does have projectors. There's no BMW with factory HIDs and no projectors. All factory HID bmws with projectors. Also it's not magnifying glass, it's lens, they help gather lighting pattern equally on the road, so light is even on road, and projectors also look better than non-projectors. If you have Xenon headlights, they're projectors. Btw you, Waveho, have projector low beams (if it's your car in avatar).

Thanks for the info, Vadim. I do indeed have projector headlights now...however the stock halogen headlamps that I removed were definitely not projectors, but had halogen bulbs and the lens was diffused. I do understand though that it is not exactly a "magnifying glass," but I meant to say that it sort of looks like it from the outside--it's a large hemispherical glass lens. Mine didn't come with HID, so I'm not very familiar with the stock or aftermarket setup of those headlamps.

I'm still a little confused, maybe I wasn't clear enough. The original headlamps that came on the car had a clear lens covering the low beam completely. The xenon headlamp lens have a hole cut out in the center. they both had refelctors in the housings.

I'm in the same boat. I brought Projection Halo's for my 97 528i and connected them. They were a direct plug match with my stock wiring, but had an extra connector above the low and high beam connector. I don't have daytime running lights and the rings aren't coming on with the regular lights. Any suggestions.

You need to connect the halos by tapping into the corner lights for power if yours did not originally come with halos.

Everything will be plug and play in regards to High and Low beam. If you purchased Depo's, then you will have 2 extra connectors on the back of each headlight. The Yellow and Black connector are for Halogen lights, just tape them up and disregard. The Blue and white wired connector is for the Angel eyes. The positive (blue) will need to be tapped into the middle of the 3 wires going to the parking lights on each side, the white wire going to any of the other 2 remaining. This can be done by splicing and buying connectors to make it more clean and easier for another HID/AE replacement.

So here's a question. I have Xenons and, be default, projectors. The cutoff has become blurry yet my adjusters are not broken. I just can't get the lights to align such that there is a sharp cutoff. The vertical lines (the /) are not in alignment.

Ideas for this horizontal adjustment problem?
