CONVERTING XENON TO LED POSSIBLE?
2007 E550 Bi Xenon headache, Can i convert to LED ?right side is intermittent on and off . Put the light switch to OFF when I get a dash code and light goes back on for 2 minutes and out again.
I SWAPPED THE BALLAST AND BULB with the leftside good ones .
Put the MB computer on it to see if any codes and YES . It reads "defective right side headlight "
I bought another RS headlight assembly from a donated E550 with a busted housing . I stripped it down and removed all the internals .
Now I want to remove the headlight on the car , strip it down and replace all the internals ( as best I can ) with the parts from the scrapyard donated car .
My question is : Am I wasting my time ? This scrapyard headlight already cost me $200 and hours to disassemble the bumper ,wheels, wheelwells, etc .
IF ANYONE HAS OR HAD A SIMILAR ISSUE AND COULD ASSIST ME i WOULD BE VERY GRATEFUL !!!!!!! ( sorry for caps )
I am very frustrated with this because the new headlight assembly here in Canada is over $1000 with AFS , cornering light , etc etc
HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I don't think it's really possible, you have the active curve illumination too and there was no LED option so there's no factory swap. Many convert from halogens to led, but that's simpler because there's less stuff unlike the bixenons which have the motors and ballast. Did you clear the codes afterwards? Usually it's either the bulb or ballast. Lots of times the bulbs you get on eBay or other sources are fake and they will go off and on. Could be the ballast also. Doesn't sound like the motors are gone. Did you use new bulbs? Did you get a new ballast? What happened when you swapped? Did the bad light switch to the other side? If it did, it's a bad ballast, if not, bad bulb. Missing info in your post.
Here they do sell aftermarket assemblies, but they don't include the ballast or the motors and they're under $200 so you would normally swap all the parts over. The headlight assembly is now cheaper in the US, down to $552, I think they were over $1500 years ago.

hello and thanks for your reply. to answer your questions:
1/ after I switched the good ballast and bulb from good side ( left) to bad side ( right) the badside worked for a while and then it started again .... intermittent on and off of low beam and code on dash . this is what puzzles me . the ballast I switched from bad side is working fine on the leftside ( good side) .
2/ I don't know if it is the lightsensor behind the mirror
- another bad bulb although it was changed twice . Phillips and Osram
--maybe faulty wiring going to Sam module
- etc etc etc ..
I am afraid that at the end of this frustrating BS I will land up having to buy a new headlight assembly .But I will keep searching for the problem . I hate to give up to MB's /Hella and their crap !!!!!
Anymore ideas to try is greatly appreciated and maybe when we find the answer it will help countless others that have the same headache .
be well

First thing I did was a retrofit to LED, which is basically a D2S Led Kit; as simple as plug and play because they come with a module to avoid error codes, no need to do wiring or coding. So far working perfect.
It's a DIY job but if you don't feel confortable doing so take it to a shop, it's cheap and simple; just pick the best LED bulbs possible.
