HID Xenon Conversion

Not sure what you mean by "one-piece lens"...? Are you looking to replace the entire housing or just upgrade the bulbs? Correct me if I am wrong but the '04s have projector style halogens, right?
**Sorry for the picture size, not sure how to re-size from the web... if someone tells me how I will shrink it**

The kit is spot on, I just thought their was a difference I should be looking out for, and it looks as though the only difference is the bulbs. I will go with these.
-Is their a write-up on how to take the headlights out?
-And is their a kit for the high's as well? I would love to have both high/low
-And did you get the 35w or 55w?
Thanks, you have been a world full of help


p.s and by the way, do you have pics with your hid's on? thanks

For headlight removal, do a search for removing the front bumper cover on a w211. I did mine one side at a time, which facilitates doing it yourself with only 2 hands.
hope that helps.
Swapping my headlights lens are faded/ blurry can't see far ahead
Thank you in advance as I'll keep searching for a clear write up swap
Was gonna buy a pair of 2003-2006 w211 xenon headlights , take off bumper install the headlights plug all back in and go to dealer to activate the xenon lights , so I'm asking what else I might need I read all threads nothing was fully clear all was jumping convo ( YES OEM Headlights )
Hi guys, winter time is coming up and would like fix my lighting system, I read this thread and read the thread to convert to from non HID to Factory HID, but ain't get a straight answer, I have a w211 e350 2006 with non factory HID's.
I would like to replace the entire headlight with factory HID's, do I get non adaptive ones or adaptive ones? plug and play besides going to the dealer to activate Xenon System on?

Adaptive. Not useful without rewiring for level sensors etc. That is an ordeal and a waste if $$ imho
Non-adaptive. Is there there such a thing for factory headlights?
I went the route of making my stock non hid headlights to bixenon, by replacing the projectors. I didn't bother with dealer reset. I get both headlights, inboard and outboard, turning on for high beams.
no shortage of opinions out there but factory hids aren't necessarily the best you can do for your ride. Those are however the most expensive option to my knowledge. Also things like the ballasts are a fortune to replace vs quality aftermarket etc.

If you are buying an OEM set of bi-xenon headlights, I would strongly advise against buying a new pair as they really won't work correctly in your car, and they are quite expensive. I don't remember the details and someone please correct me if I'm wrong but I believe the connectors required to make those lights work are different, as there's different voltages on different pins and such.
There is a member in the W211 AMG forum with an 04 E55 who swapped in bi-xenon headlights and he went a different route that may work for you. He purchased Depo brand headlight replicas from ebay, or this, and swapped in bi-xenon projectors from theretrofitsource.com
If this is the route you want to go, the projectors are evox-r and are virtually plug and play, then purchase your choice of D2S bulb, phillips 85122+ are good, Osram 66240 CBI are better.




I'm almost ready to pull the trigger on the Evox-R's from TRS for my '08 E350, but I want to see some comparison shots with the OEM E55's.
The general consensus is that the Evox-R's are better, but many have expressed disappointed with them. (it also appears there has been some revisions to the Evox-R's in the past few years but I haven't found any solid info on this). I'm also curious if anyone has gone with a projector other that the E55 or Evox_R.

I can take beam pattern shots for you tonight if you like. I am using evox-r with osram 66240 cbi bulbs. I do not have beam pattern shots of the original hella E55 projectors, but I don't think it would be too hard to find online. I have had the projectors swapped for about 2 months now and my impressions are as follows - these are of course all compared to the hella E55 projectors:
-the beam on the evox-r is wider, as in, it is brighter at the wider parts off to either side of the car.
-The distance seems about the same, if there is a difference between the two, I did not notice.
-The cutoff on the evox-r is much flatter, and the step is much smaller, than the E55, this might allow you to aim a bit higher without risking blinding anyone.
-The cutoff on the evox-r is a pretty visible blue, and thus the flicker other motorists will see will also be blue; I believe the E55 has more color and more color variance in the flicker.
-The bowl in the evox-r projector is highly polished. This in turn can make the beam pattern in the foreground (close to the front of the car on the ground) appear streaky. This effect is not really noticeable when driving and with bright (new) bulbs it's really a non-issue.
-The evox-r do not come with a foreground limiter. This is a plate that blocks a large amount of light from flooding out to the ground immediately in front of the car. This can be very distracting as it creates a large contrast and makes the eyes have a difficult time adjusting between the ultra bright foreground and everything that's dark above the beam cutoff. If you are swapping from Hella E55 to evox-r, the foreground limiter plate can be easily swapped into the new projector. If not, a foreground limiter can be easily made though with some thin sheet metal and tin snips.
-The evox-r do not have a "squirrel finder" which is a deliberate scattering of light above the beam cutoff. It can be helpful for lighting signs and other things overhead, without offending oncoming motorists. The hella E55 does have this, as do most OEM projectors. The evox-r has zero light above the cutoff.
-The hella E55 has a fresnel lens, which is sort of frosted and concentric circles on it's surface. This aids in making the beam pattern much more uniform beam spread (could alleviates streakiness that is seen from the polished bowl of the evox-r), but also makes the cutoff a bit less sharp. The evox-r comes with clear lenses and this makes the beam cutoff ultra pronounced and sharp, and makes the color at the cutoff much more visible.
-The bi-xenon functionality in both projectors are identical and use the same connectors making it plug and play with the headlight harness.
I am happy with the projector swap, I don't think I will be going back. As you can see there are some disadvantages to the evox-r vs OEM, but there are a lot of positives as well. Most importantly more light. I don't think any other readily available projectors out there will fit the W211 light housing without some modification.

I used Amp pigtailed ballasts. I drilled a hole in the round headlight cover. I put a rubber grommet in there. Then deconstructed the AMP connectors so that I could pass the wire through the grommet, then re-assembled the connectors. My ballasts are older and too large to house inside the headlight. I recently read of someone putting the ballast inside the headlight.
I'm happy with the conversion. One of the ballasts is starting to flicker, if RS doesn't replace it under warranty (I think it's out now), I might go 50W for a ballast upgrade.
Let me know if I can help in your adventure. Getting the bumper cover off is only part of the adventure!!

It seems that everyone is after the sharpest, bluest cutoff, but to me it seems counter-intuitive. I would think a little bleeding over the cutoff would actually be quite helpful in seeing what's above the road. I think the same is true with the two shields, in that the E55 shield will allow more vertical visibility (i.e., seeing a large animal or person instead of only their feet, dim road signs, etc.).
I really like the thought of the wider beam on the evox-r, and that's what I want to compare against the E55 - just how much wider?
I'm giving some thought to getting both sets of projectors and using the E55 shields and foreground limiters on the evox-r. I just don't know if it would be worth the added expense. On the other hand, the E55 projectors with a clear lens may be just as good. I think the difference in beam width will end up being the deciding factor for me.
@Bill: If I were you, I'd give serious thought before going to the 50W ballasts. I've read that they burn your bowls prematurely - especially on the E55's. That's your call though - may be worth it at the expense of replacing projector bowls in a few years.
I'm currently using a rebased H7 kit with the XB35 AMP ballasts. I'll probably stick with that setup, but I'm seriously considering the Denso slim ballasts (I just love how my W203 with factory xenons light up to full intensity in a split second, vs. the Morimoto setup on my W211).

My understanding is that OEM bulbs like Phillips and Osram can be run at 50W if someone wanted a stronger ballast. The OEM bulbs can tolerate that extra power without getting too hot to melt bowls, but I wouldn't try it with other aftermarket bulbs or even Morimoto bulbs unless they are specifically made for 50W. Besides, having so much bright bright bright light immediately under the cutoff, and pitch black above the cutoff can actually hinder your ability to see at night driving depending on your location. If you're in the city with a lot of light around around you it wouldn't be as much of an issue, but if you live in the sticks, the contrast between the two would put quite a strain on your eyes to see what's in the darkness above the cutoff.




Of course we all know that beside its uniquely colorful cutoff, the E55 is not the best performing projector out there. Thus, I'm looking for something in between. I'm over the ricer phase and safety definitely comes before looks, but I do occasional long distance driving on rural roads (bobgodd, you might know what I'm talking about: the old 94 from Rancho San Diego to Campo) thus why I'm looking for a little more performance.
Just out of curiosity - has anyone tried Fresnel lenses on the evox-r? It would be interesting to see the effect.

Did my low beams and fogs with 5k kelvin (hardly any blue color emitted). No probs for a little over a year. I believe the ''08 uses an H7 (pull the current bulb to verify. My manual made a mistake on the fogs), and I also believe the SBC was eliminated with MY '07.
All Plug 'n Play. Hardest part of mod is getting the rubber grommet thru the rectangular opening in the center of the sheet metal bulb holder.
Mann, I had a shop do some tint and the HIDs, its giiving me a check engine after 2 months. My mechanic said it was because of the HIDs, killed the ozone sensor. he read more on MBworld too. Im just not finding the right solution. Link me to a website or something you know will work 100% and make the light go away haha. its a 2008 e350. only 65k miles on her.
