Headlight Conversion

Hi everyone a week ago i bought my first mercedes and it’s a 2014 w212 facelift e200 the car is really great but there’s a few things that bug me about it and would like to take your opinions about them, so the number one thing that bugs me about the car is the fact that you could buy it with halogen headlights which unfortunately my car does have, so i am asking if any of you guys did the conversion from halogen to the LED’s, did it take too much time or did you get many faults or errors on the car’s computer and is it worth the money or should i just stick to what i have and if you dont mind me asking how much did it cost

Thanks in advance

You are mistaken about what you have...

If you bought a 2014-2016 facelift, at mere minimum, you have 5K LED low beams and 3200K Halogen high beams. These can be upgraded to Phillips Diamond Vision H7 Halogens equal in 5K brightness to the low beams simply by replacing the bulbs.
Amazon Amazon

No faults, errors, etc, just white light. You can buy LEDs for the high beams, but there is no need to do so. The LED aftermarket beams available have huge heat-sinks attached to the back, for which you will need to make room behind the headlight housings. Not easy to do, and results vary wildly, so be forewarned.

Upgrading to Mercedes full LED intelligent lighting is rather expensive, those headlights are like $1600 each plus $800+ for the power supply for each side.

Slapping Chineseum aftermarket H7 LEDs in the existing buckets, you have to make room for the massive heatsinks as someone said, and there just isn't much room behind the buckets.

My only goal was to eliminate the yellow light in the high beams, recognizing that I seldom use the High Beams, and really shouldn't care. The Diamond Vision solution noted above accomplishes this, as the light is bright white, matching the Low Beams. So I rate them as excellent.

This was the very first "mod" I performed on my car, almost 3 years ago. The lights have held-up well as High Beams, as I live in a Suburban area, and have very few occassions to burn the High Beams at all. The only trick to installing them is to be certain you handle the bulbs with tissue paper to keep your finger oils off the glass. Just $25, one and done.

Xenon headlights are nothing new... I could have bought them as new on my first Mercedes... in 2001. Yawn. The Intellignet Lighting system is interesting, but not remotely worth $4,000 to install them, and trouble-shoot unknown electronic issues that follow. An idea that's DOA to me.

If I HAD to spend $4,000 on anything, I'd spend it on a set of new wheels and tires. At least you use the tires anytime you drive the car. You use the lights only if and when you drive at night.

I don't like anything that puts a heat sink inside the headlight assembly. No place for the heat to go.

I hated the weak halogen lo beam output. In 2015 I installed a Morimoto 35w HID setup with 5k bulbs and CANBUS connector for lo beams. I didn't care about hi beams because I never use them so stock was fine. Has worked perfectly since, one of the best changes I've made . The beauty of using the halogen projectors is that light cutoff is almost perfect, no light scatter like in regular reflector housings, so no blinding oncoming traffic. The cutoff height is right plus it follows North American driving direction. Slight rise on the cutoff towards the right or curb side.

I've done a couple of full retrofits on other vehicles using ML55 bi-xenon projectors ( they use DS2 bulbs and have the internal shutter system). When I compared the lo beam light output and pattern to the HID in the stock E350 halogen projectors, the ML55 was slightly better but the HID was very very close. I think the difference was in the bulb type and the positioning of the shutter. Note that the stock projectors in my car are lo beam only, so no shutter. Makes me wonder though if the W212 PS-2 xenon equipped models actually use the same projectors. Dunno.

I know the headlight bulb choice will always be under debate, I'm just relating my particular long term experience in my older 2011 model. Might be completely different in newer versions.
