@degeja the led with the fan, what did you do for the light cover? Do you just leave it off? Man the low beams even putting passenger side back in was a pain in the *****, can’t see ****
The car works must have built in resisters(or something) -- it says it uses 30 watts ;
standard H7 halogens are 55 amps.
Most other LED brands are much less power; ie Auxito is 16 amps.
Most other LEDS only work without causing the bulb out alarm if adapters or resisters are also installed. The resusters increase the current draw. The light bulb out warning apparently works by sensing low current in the wiring to a bulb.
I installed resisters on a previous car (2012 E350) with different brands (troed several) LED that have low current load like AUxito.
The Car Work was the only one I found to work right out of the box without adapters, resisters or anything.
True plug and play.
Some LEDs worked but the light output was worse than the Halogens-- even though they advertized 20000 lumens or 6 times halogens-- was just hype.
Couldnt see to even drive thru the neighbrhood.

typically an LED will use 10% of the power of a Halogen at the same brightness, but these replacement car lamps have to have load resistors to 'fool' bulb-out sensors (commonly misnamed as CANbus). These load resistors add watts
Went thru that on my 2012 for months, finally put in resisters in low beams. Did have spare H7 halogens in between trials.
And the LED that finally worked with resusters wasnt much better than the halogem. ANd resisters in parralel mounted in the fenders isnt easy to do.
THE Lasfit worked fine on the high beams in the 2012-- had a kit in between the wiring and bulb.
My 2016 has low beams LED standard and are really good.
The car works are 30 amp but since they still flicker in you car I looked around and the Amazon Novsight H7 70 16000 Lumens might work.
They also list a couple with 50 watts but lower lumens.
I ordered lasfit resister, supposedly it’s brand new model , if this don’t work I’m giving up and getting standard halogen, should be in by Wednesday or Thursday….. I’ll keep you posted
WDDHF5GB4AA082600 That’s my vin
and I read something about coding a CANBUS whatever that is
Hi there,
I'm hoping you can help me figure this out. I have a 2010 E350 4Matic - the VIN is WDDHF8HB7AA103889
I want to replace the low beam Halogen bulbs with an equivalent LED H7 bulb but I'm not sure which one will fit as I understand that if the car can only take a screw in type base, then an LED bulb won't work. Apparently only the cars with the spring loaded tension clip can accomodate an LED bulb. I have no idea which one my car has - screw in or tension clip. I'm hoping someone can point me in the right direction.
The LED bulb that seems to be a potential replacement is the H7 by Sylvania. If someone has experience with a better alternative, please let me know by sharing a link.
I have attached a pic of the car as well as that seems to an important point regarding facelift vs. not.
From what I learned, key things
It is hard to twist the metal retaining clip into place! - and dropped one in the housing - which is horrible hard to get back out.
Pick a good bulb and make sure it is a CAMBUS bulb when you do, get one that has a fixed ring so the orientation is correct when you insert it. You have to insert the bulb and twist the retaining clip all with one hand...so takes some dexterity.
I did this for my friends E350 and never had to replace the bulbs in 2 years. No issues with beam cut off and alignment, etc. and 2x as bright.
Cheers, I hope this helps.

Reason: adding Note to get Canbus bulb
Hi - I opened a few threads years back about LED bulbs for our cars.
For the E350 that is Halogen, yes you need a H7 bulb and then a metal retaining ring. for each side.
Check what style you have - I forget but it should be something like this (I have no affiliation to this vendor or item) Retaining Clip

I bought the Techmax H7 bulb and I finally got around to swapping out the passenger side headlight today (the temperature finally warmed up to about a degree above freezing) as that one is easy to get to. However after installing it, it will go off after about a minute and then 5 seconds later it comes back on and then a minute later goes off and this just keeps on repeating........
Is this behavior because I only installed one LED headlight (the drivers side halogen bulb is still working) ? I can't really install the drivers side headlight right now as that requires the wheel fender lining, a splash guard and front drivers side wheel to be removed and it's just too cold to do that now. I don't have access to warmer environment/garage at the moment.
I'm wondering if I should return the Techmax LED's or just wait till spring and try this again?
I tried installing few different brands of LEDs and had to buy one of them decoder boxes but had nowhere to put the decoder box so I’m done trying it’s a pain in the ***
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 that little metal fitting for them to fit in the slot but after doing some research I kept seeing 9005 headlight bulbs come up as a popular option. 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
Go with Diode Dynamics, Morimoto, or GTR Lighting as they are well regarded and fit properly. Check your exact bulb size first since most use 9005 for high beam and H11 for low beam but confirm yours before ordering. On the decoder question just grab one with the bulbs since Ford's computer monitors resistance and LEDs often trigger a warning or flickering without it. Some people get away without one but it is hit or miss and they are cheap enough not to risk it. The retainer clip you mentioned is usually included in the kit anyway.
