i have a 2008 s550 and I am doing the front bumper facelift next week. I thought that since the bumper will be off it would be a good chance to change out the bulbs in the headlights to white leds. I wanted to know if this is even possible (and would I keep the dimming feature when I take turns), and if so what size bulbs would I need. Any recommendations on certain brands of bulbs?

Here is my current headlight with the bulbs I want to change circled. I ma not do the turn signal because i dont want there to be any problems with error codes:

For the size look here https://www.sylvania.com/en-us/appli...s/lrgmain.aspx

For the bulbs search ebay for error free led bulbs....

What are the names of the bulbs though? I know one is turn signal so I got that, but what are the other two called which I have circled? Courtesy light?

The side parking light are T10 w5w fitting.
The cornerlight is h7 fitting (i don't think putting led on the corner light is a good idea because it wil not produce enaugh light) try use h7 osram 5000k halogen
And the turn signial is PY24 fitting
Always use error free leds

so going from left to right on the bulbs I have circled:

1. (leftmost circled bulb, towards middle of car) - would this be T10 w5w ? Can I get a LED for this or is in not bright enough?

2. (next one to the right, below turn signal blinker) - h7 (this is the one I would put the h7 osram correct) - this is the one i am thinking of, does this look like it will work? http://www.ebay.com/itm/OSRAM-SYLVANIA-H7-X-1-SET-BULBS-SZ-2-55W-HALOGEN-HEADLIGHT-5000K-OE-12V-GERMANY-/140617638369?pt=Motors_Car_Truck_Parts_Accessories&hash=item20bd76e1e1&vxp=mtr
3. next one above, turn signal - PY24 (I can get a LED for this correct?)

Ok i got it now, thank you very much.

I did buy these H7:

do you think they will work with no error?

Also here is what I bought for the turn signals:

and for the T10:

The H7 should work fine. I have similar bulbs that i installed as well to get ride of the yellow. For the T10, that is the same bulb I am using there as well. As for the turn signal, make sure you measure the height of the bulb as i purchased a set and it was way to tall to fit into the headlight. If you look really closely, there is a shield on the bulb that only leaves a bit of space. The one you have in the picture looks a lot shorter than the one I originally purchased so it might work. Post pics after your done!

For the T10 wedge bulbs (same used in many of the interior and license plate lights) I have had success with these http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=251465930473&fromMakeTrack=true&ssPageName=VIP:watchlink:top:en
They are high quality and look great, no issues so far.

Anyone know how to replace the t10 wedge bulb in the head light?
I tried accessing it thru the fender by turning the wheel but I can't seem to get a good enough grip to take it off
