Hmmm... so i think im officially tired with the sub-par cutoffs from my depo p46. Your diy shows a massive overhaul going from halogen ~> FXR. How difficult is the swap if im just going from P46 Projectors ~> FXR . Will the FXR fit nicely in the P46 projector housing? Or are the cutoffs something you can fix separately.

They went from halogen to fx-r, but they used P46s as the housing to mount the FX-Rs in. Cutoff on the P46 is probably impossible to fix without replacing the projector w/ something like the FX-R, since the projector itself just is not designed with very good optics.

If you had OEM AL projectors, it's pretty easy to mod them to have a much sharper and more colorful cuttoff. You also get a good bit more light. If you can get your hands on a set of those cheaply, it might be worth it...


Cutoff of modded AL projector


Modded projector left, stock right. Note that both projectors have the same bulb in them. Only difference in the projectors is that the driverside has a clear lens, and the shield was bent backwards very slightly (slight enough that the bixenon functionality works fine).

snowcatxx87 how did you do this?!

I've been reading threads for days for a solution and have yet to figure out how I am going to run power to quad projectors + bixenon function with the stalk (push/pulled).

Anyway you could add some detail to this? Right now I have the lows working, and flash to pass turning on the inner project (previously halogen). Bixenon (red wires) not yet wired.

TIA

I programmed the LSZ module of the car to allow Fogs/Highs/Bixenon to all come on. It is not that hard and you can brick your car. Search around the internets... or my username.... on a different BMW forum.

To put these in an M3, all I did was take out the original chrome "inner" parts and swap with the modified one I had already retrofit (the plastic piece that the Projectors are mounted to.

I just slid that piece into the OEM housing. Easy peasy!

I'm buying myself an M3 quite soon; am I correct in believing that facelift sedan headlights can be used on prefacelift coupes if you swap the outer lens and inner trim? I've got a friend with failed ZKW headlights, so I'm thinking about selling him my headlights for cheap, and then spending a little more to get Caesar to do the TFX retro on the ZKW housings.

Does this retrofit apply to regular halogen head lights? I have halogens since my bimmer is a 2000 328i. And they didnt have xenons/projectors then.
I'm assuming it should be the same thing.

Retrofit requires you to cut stuff up. So, yes, it should be the same thing.

essentially the same, but the only difference is that you will have to modify the halogen frames. (make holes so you can fit the projectors)

Waste of money. Save yourself the $400 and hassle of selling your headlights and just cut up your halogens. You'll still need to cut up the p46 frames to get the FXR to fit properly.

One thing that's kinda tricky with the halogens is aligning the projector. It's not supposed to sit parallel to the edge (if you end up mounting the projector parallel to the frame, then your output will be angled pretty badly when installed on the car). When doing the retrofit on a car that already has projectors, it's easy enough to just follow the line formed by the screws... there's no such visual guide in the case of the halogens.
