LED Projector Retrofin of Bi-Xenon Headlights

G'day. I am looking for some guidance on Bi-Xenon projector replacement options, specifically the latest Bi-LED retrofit projectors. My primary goal is improved lighting for night-time highway driving.

Vehicle:
E90 2007 328xi. Non-Adaptive HID headlights with functioning auto-leveling system. Functioning Angel Eye rings. Lighting is terrible; both lenses are pitted on the outside, passenger light is leaking. I need Daytime Running Lights as I am in Canada.

Proposed program:
I would like to install a Bi-LED projector in place of the factory Bi-Xenon projector, retaining the self-leveling feature. I would retain the existing Angel Eyes if I do not break them during dis-assembly. I would try and polish out the pitting in the lenses, or replace them with new European lenses, if available.

Options I have found:
I am considering the Aharon AtomLED X2 (2.5 lense) or the Aharon AlphaLED X2 (3 lense) from Retrofitlab out of Netherlands. The Kits are about 300 Euro (about $300 USD) for a complete pair of Bi-LED lights.

The other option is the Morimoto M LED 2.0 which is about $425 USD for a kit depending on options. The Morimoto is much more popular in North America and likely has better support here. Morimoto quality looks good,possibly better than the Aharon, but it is difficult to tell without seeing both in person.

Spending more money:
Ideally, I would like to replace the inner halogen lights with an LED high beam with a DRL feature. Retrofit lab have their Aharon LED Highbeam projector for 75 Euro. Morimoto has the mini HB and Profile have the Hi-Lens 2.0 LED. The Morimoto and Profile options are about twice the price of the Aharon. I am not sure if the high beam modules will fit easily in the existing inner halogen locations.


I have read through several posts, but there are very few referencing LED retrofit projectors (Estonian is one). Dakine_Surf has posted several times and is an expert in this business, and appears to offer custom headlight services. I would like to try the DIY route, but would welcome expert advice.
Can anyone share their experience with any of these products or the installation?

Thanks,
Peter

Hi

I've done projector swap on all my cars as generally HID are used also during daytime by previous owners this just burns up the projectors over time.

Daytime lights ... something like LEDs in fogs is sufficient.

1st i would fix the leaking light. The condensation ruins everything there.

What comes to retrofitlab i also got some stuff from there - the bi-xenon projector kit for e90 (this was when they didn't have LED kits yet).

Observations:
1) Received adapter was wrong and i had to make my own - this is the most annoying part with any projector retrofit if you likely need to use the car next day. Quickly fabricate something that is durable.
2) The D1S socket holder is designed not so great. Small screws slightly push the D1S bulb off from correct seating position = slightly foggy cutout line.
3) Obviously the projectors themselves are great.

If i instead went with Bi-LED probably what would encounter:
1) coding part - probably sufficient to just disable cold/hot check.
2) Bracket mounting system fabrication (if they send you wrong one or none).
Here it is useful if you have a blank aluminium sheet and something you can modify it - just to be prepared.
3) Open up the headlight vs removing OEM projectors from the back headlight opening.
I removed the projectors from the back cover but it was ... time consuming. It is possible! it comes out with weird angle.
4) The wiring part. For the shutter energize i just wired them parallel with high beams.
Sure there is dedicated wiring but i didn't find the correct combination to get it work 100% times with it (without them throwing fault code & shutter working always as intended).
Main power - probably just rerouting 12V source directly to LED.

Most annoying part is fabricating adapter (without CNC router) - everything else is doable.
Here's image of HID projector in our car. The 3 point fitment is problematic for any aftermarket product.


If you succeed with LED projectors there are true 55W H7 LEDs (not just theoretical diode power that is littered everywhere on market) that output is pretty darn close to D1S.

Probably would go with the retrofitlab because it is EU located - less headace with the toll.
One is 2.5" glass other is 3" glass. Can't find output ratings but one is 120mm other is 132mm length wise.
I would ask them to send or even pay extra for the adapter that is guaranteed to fit.

I'd do this instead.

1) New OEM Lenses
2) Modded Hella Gen3 D2S ballast (50w after it's all said and done)
3) G5-BRT Projectors + adapter plates
4) XNL or XV2 D2S bulbs.

LED or Xenon

Curious why you would stick with Xenon technology, rather than move up to LED projectors. I was under the impression that the latest LED projectors were as good, or better than the best xenon kits. They may be more expensive, but their longer bulb life and absence of ballasts should pay for themselves in the long term.

My question is; Has the LED retrofit market matured to the point of competing with the best xenon projectors out there?

Cost. If that's not a concern, then I'd probably dive into a set of Morimoto M LED 2.0s.

Also consider that if the LED in the LED projector goes bad, you have to bake the entire headlight again to access and replace the projector, whereas a Xenon going bad is just a bulb swap. That alone should be a dealbreaker.

Edit: having driven with both Osram CBNs on stock ballasts and NHK Gen V LED projectors at the same time, the NHKs are definitely brighter. I would suggest getting the NHK Gen IV or Gen V. Lightwerkz did a comparison on YouTube of the Gen IV with the Morimoto MLED and the Gen IV frankly seemed a lot better.

Hey Peter any update on what you chose or decided to do in the end? I am also looking at the LED retrofit projectors on retrofitlab!

Hi Inxguy - Per #3, where do you get the adapter plates please? I have one set and found that they fit the Morimoto mini D2S 5.0 as well but don't move(non adaptive). A friend got a different type that retain the LCI adaptive function using the G5 projectors. Hunting for these brackets.
Thanks
P.S. I'm also a fan of the modded Gen3 Hella ballasts cranked up to 55W.
