It is of no use to the W204.

what kind of led would fit into the festoon bulbs place? because i'm thinking of doing an interior color scheme, but i don't want to get all the led's and not have a match for the rear.

(NVM did some research and answered my own question)

to anyone else who wants to know: to find the bulbs you need, do an ebay search for festoon led's, and look for ones that are 44mm.
44mm is the size of the oem festoon bulb

Ohh no cracked one side, anyone got a part number for the front dome right hand side lens? (or both lol didn't change bulbs in the end)

Or am i going to have to buy a new dome unit?

Thanks

is there a way to remove the lights or replace them, the ones under the rear view mirror. im trying to replace that faded orange light

kaku

that nifty faded orange light acts as a "night light" and is barely noticeable. it's supposed to help illuminate slightly the gearbox area..

ARGGH!!! Should've read the entire post before I tried to do it on mine. I've cracked the cover now and everywhere I asked I need to buy the whole light unit. MB Australia sell it for $670!!! WTH!!!!

Hi there

i am going to swap the rear dome middle bulb to LED. but i am confused about what bandwidth of the LED bulb should i use. should i use 31mm, 36mm or the 42 mm one??? or they basically all fit ?? please help me answer this !

thanks in advance

They don't all fit. You need to measure the length of the bulb. From the picture it looks like 40+mm, but not sure exactly without actually measuring it. Never got around to taking apart my rear dome to LED swap.

I got led in my rear dome

AZN Optics

Randy, you remember the size of your rear festoon?

ks4life

not sure thou....

Do the interior front and rear dome lights on a 07' E350 pop off the same way?

AskDrTodd

Did this tonight, the rear one is in fact a 44mm. The rear one is notched and I popped it out from the notch and it popped right out no problem. The front ones were pretty hard to get out, note that they clip in all around so you want to pull from the side facing the rear of the car so there is no lateral pressure applied to the tabs that clip in toward the center of the light. (i.e. I cracked mine and I'm not super happy about it)

AZN Optics

Actually, it's more 42mm. I just recently popped mine out a couple days ago and my 41mm work great. 44mm will probably also work though because these are end cap festoon grips which have some flex instead of dual clips which you have to be pretty precise.

I want to change the bulb for all 4 courtesy door bulb. Anyone now know to do that. Also my courtesy light cover is red plastic so anyone now where I can get some clear ones. I want to put Blue LED on all for doors

thanks alot

Sorry I don't have picture for door lights, but I changed on one door light with an LED bulb. Use a flat screw driver to pry it out at either end; it is just a bit tighter than some other lights.

May I ask how to turn off the trunk light so that I can replace the bulb?

C300CA

I don't think there is a manual way to turn it off. If the trunk lid is open for more than like 5 minutes or so, it turns off by itself. I just use some cloth or even bare hand to quickly pull it straight out, very quickly so my fingers don't get burnt.

I followed instruction and tried popping out the rear dome light, but found it is not as easy as the front dome light. I am afraid of breaking it. I'd appreciate any more hint what the best/easiest way to get it out. Maybe it needs more force but I don't have a feel how much more force is needed. I noticed a gap at the back at the slot (designed for taking it out?) but rest of the area didn't want to come loose...

AZN Optics

Yeah, the rear is a little scary, but just give it a little effort and it'll pop out. Once I did it once on my own car, it was easy to do repeatedly. I was able to find a plastic wedge tool that works great at popping interior housing. Picked up about 50 of em and now including with my interior lighting package.

dsammy

I also didn't read entire thread before doing it. crack the cover a little. The creditcard method worked like a charm. Now my front dome light have blue LEDs... Looks sweet. thanks for tutorial

desa

The front interior light housing must be the worst MB design. The light cover cracks easily. Have tried using the credit card and it have managed to get it out 5mm or so but no knowing which end to pull, gave up as I couldn't see where the tabs were.
Do you pull from the side or from the front or rear? The pictures posted by OP appears to be from the side.....
MB must be running out of replacement front lamp fittings by now!!

I just opened both the front and back to see if I can swap the bulbs to LED. I attached a pic for reference, AZN LED on left and stock bulb on the right. Now I need to order more LEDs and change all of them.
