I want to put LEDs bulbs in my headlights, I already have them in parking lights and headlight bulb went out so I figure this the time to do it…. I’m stuck idk which ones to buy that fit, I know I have to buy a that little medal fitting for them to fit in the slot. Basically my question is which LED lights/brands are good and also do I need a decoder, some people say I need one some people their lights work without it. Any input would be great… thank you

Facelift or Prefacelift? Halogens? or Xenon?

If you post your VIN, we can see the datacard and see the lights option code.

WDDHF5GB4AA082600 That’s my vin
and I read something about coding a CANBUS whatever that is

Yours looks like a 2010 E350. CANBUS is a system to detect when a bulb is out by detecting low electrical current to a bulb.
Many LEDs are low electrcal use (low amps) -but they trigger a light out warning.
Some require adapters, resisters,etc. to avoid light out warnings.
Some looked dimmer than the Halogens regardless of advertized brightness.
Newer versions and manufacturers seem to show up every day.
I traded my 2012 E350 on a 2016 E350 that ale=ready had low beam LEDs and H7 halogen hi beams.
I installed a 30 amp LED I found a 30 amp LED bulb on Amazon and installed as direct replacement on the high beams with no adapters etc and no bulb out warnings.

I used CAR WORK BOX H7 LED Headlight Bulbs w/Fan, 1:1 Mini Size, No Adapter Required, Non-Polarity Plug and Play, 6500K Bright White All-in-One Conversion Kit but there may well be others.

Just my experience

When my E come with LED, I did the conversion in my GLE.
It is using H7 bulbs, who are mounted with adapters, so since LED bulb is having thicker base, I had to buy new adapters.
The access on GLE to low beam bulbs is via inner fender and relatively easy. I also tried high beams, but factory adapter is coming with side extension and I could not find 1 for LED bulb. After 1 hr of trying to put universal adapter, I gave up.
I have fingers well trained for precision mechanics and working by touch, yet the job turned above my skills.
Starting point - remove your bulb and make sure you have correct parts.
Here is comparison. Telling the truth, when 70W LED has different color, I don't see much difference in light intensity.

The yellow light beam on the right has a better focus than the white beam on the left , yes?

This issue is not having the light source properly focused.
This is not easily done unless the bulb socket is adjustable... then you'll get brilliant road lights straight far ahead nearly like OEM.

These LED do not lock in position, they can be rotated while in their adapter. Just installed LastFit on the ML, and I had to check they were oriented correctly.

Plug and play, built-in adapter

There is also a MB Pro1 H7, I think a bit different adapter.

I was able to use LEDs on my E and GLE without a problem been a year and half now and this has a lifetime warranty

https://precisionled.com/mercedes-e-...2009-2015.html

this is plug and play it has a canbus circuitry and don’t forget to ask the for the free metal adapter .. and this is adjustable to achieve the correct light pattern for your car

edit.. I do not work for this company but have been buying and doing warranty exchange on their LED bulbs for over 5 years now for the smaller side marker LED’s and will be buying for high’s pretty soon I completely trust this company for their lifetime warranty which is good so if LED’s fizzle out I will be getting a newer LED build/circuitry .. No company wants to give away their product just like that for warranty so I would presume this company to stay afloat will search for the best technology to make/ sell to outlast the car itself.. give a try you won’t be disappointed, yes I almost sound like I work for this company LOL .. I don’t.. lol

Per my check it is focused OK.
The issue I see is that when rounded H7 bulb spreads the light more evenly, the LED, having light on 2 sides makes the center brighter, than the sides of the beam.
This is up to personal preference what you like. For me more light on the center is better.
This is how the beams compare on the terrain. For me the left (LED) beam spread is better.

"canbus" circuitry, hah hah. that means they have a big ol' fat resistor in parallel designed to suck as much electricity as a regular halogen so the bulb out sensing circuitry works, which means they run hot as heck.

donny79

I got these, they have the canbus, they should work
You

Hmm- mine was straight in. Picture shows a right angle. Picture isnt same as my H7 halogens which are straight in from the OEM male plugs.

donny79

I tried finding lasfit I seen others recommend but Amazon says it don’t fit my car, none of the lasfit for some reason … ya your right I see what your saying about the right angle , I got these from Amazon if this don’t fit I’m going to go with precision led, I guess that’s it’s own site but I would of never thought this would be such a difficult project finding a bulb 🤷‍♂️🤦‍♂️

I've put Auxito LEDs in several halogen cars with very good results. I use their base model LEDs in whatever size, 9000 lumen, 6000 kelvin.
https://www.auxito.com/collections/h...gen-light-bulb
for H7's

be sure to install these so the leds are on the left and right sides of the lamp, so the flat plane in the middle is vertical.

I went thru over a dosen different brands for my 2012. I used lasfit on my high beams for my 2012. It is direct fit and no adapters.
They didnt have a direct fit for the low beams.

For my 2016 I found the Carwork for the high beams and should work for the low beams too. Direct fit just like halogens.
The hi beams are as good as the lasfit on my 2012.

degeja

Low beam bulbs are a real pain to change. Suggest you do high beams first,

juanmor40

@donny79 , what type of bulbs you got on the low beams? H7 halogens, or HID-D1S?
the high definitely are H7.

Here is an old thread, no LED, describing all bulbs for the 2010 W212
https://mbworld.org/forums/e-class-w...ml#post4896115


​​​​​@mike919 just upgraded the W166 HID-D1S to LED as well, https://mbworld.org/forums/m-class-w...ml#post8821288

degeja

I dont see HID listed as option in the VIN decoder for headlights.

donny79

My low beam is out , I have the H7 halogens in now

donny79

I really just don’t understand how some leds have 90 angle for the 2 prongs and says it fits, yet the one with straight 180 2 prongs say it also fits, **** is annoying because I’ll get it home, get ready to do this and it won’t fit ….. I went on Amazon and none of the lasfit h7 Amazon says it won’t fit, so I got the beam tech with 90 angle says it fits. I went on xuieto says 90 fits but also the 180 fits, I’m thinking well which one is it, they both can’t fit

degeja

went through that; its advertising. ANd many fit straight but trigger the bulb out.
You can just try the one I have but you seem to insist on some others that may or may not work.

Good luck.

donny79

No I’m not insisting at all, I’m just confused, I already ordered that bulb before everyone started commenting , I don’t want to get pulled over for a dumb headlight, after hearing what everyone had to say after I ordered the one with the 90 I ordered the 180 so I’m just going to send the 90 back

degeja

You can get CAR WORK BOX H7 LED Headlight Bulbs w/Fan, in one day from AMAZON for $30 and it shouldnt give any error code.
Unplug old one in and plugin new one.

If you dont like it you can return.

donny79

The beam tech came today with the 90 angle but it was a plug and play so it would of worked, only problem was the whole 2nd half of it was hanging out about 11/2 inches so there was no way to close the cover….. why make an led and say it will fit when clearly half the unit was hanging out…. I’m sure the small 180 degree one will fit it same size as the oem bulb
