Problem with install LED tail light W204
 

idk but i like those lights.. ??

Check your fuses? The diagram I believe is in the trunk near the spare?

Edit:
Also, it could be different lighting pattern from OEM and only turn on when the brake is applied?

No work
 

There is no software reset for LED rear lights so that advice is wrong. Substituting LEDs for a conventional bulb in the taillight position probably triggered the lamp out module to turn on an alternate bulb since the low current flow of the LEDs looks like a failed bulb to it.

i had no idea there was an aftermarket led tail light?

it could just be that the bottom light light up when you hit the brakes. Turn your fog lights on n pull the switch all the way out. go to the back of the car and see if the light is turned on. that could be the rear fog light.

but why other lights is work? the barke and all of them is work just up light is not work?

Trying this but not work ,just the right light up is turn on!!!

when I remove the LED Socket from lamp supporter and install the original lamp it is work and it mean the electricity is flow, but when put back it to LED socket this in not turn on(just on up light)

contact the ebay seller and let him now. The solder point in the LED circuit board must have been bad on that light. Ask to replace it, or you can fix it yourself if you have a solder. Its not the car if the right one works.

L+R of tail lights is not turn on, yes you are right if one side is not turn on maybe the solder point , but when 2 sides the problem is different, today I give the direct electricity to Up LED socked and this is not work!!!!and when check the electricity of socket it is flow :eek:, oh god when it is work:bow:

and i forgot, the message in car computer is: REAR RIGHT SIDE MARKER LAMP, maybe this is help for find problem

Just shooting in the dark here, but maybe you need to install a resistor? If I recall correctly, you need something like a 6ohm 50W load resistor to make the error message go away and maybe then the computer will behave differently? :nix:

Just so we can understand your exact problem, it's the upper parking lights that are the problem? Do the lower brake lights work ok? Do the turn signals work ok?

yes I think this is work,check the pic:

please lock at pic maybe help to find problem
Attachment 185186

Attachment 185187
when brake:
Attachment 185188

see all of the lights is ok but the up light is off,oh god

today the supplier said is :
THE LIGHTS IS DESING LIKE W221,and the up light is for fog lamp.................
yes he is right, when rear fog lamps is turn on, 1 side is turn on(Up light)"this is right"
but I Thought it must like original lamp, I mean up+Dowm is turn on, and now the design of light like S class and it mean the LED tail light is work true

ive heard benz and LED's dont make good company

so.. how do you make the upper ones come on? by turning on fog lights?

yes, up lights just for fog lights(in LED Tail light), LEFT up for fog and right up side is off for always, the rear fog lights is only 1 side

overall are you happy with these lights? Were these an ebay purchase? I like em, do you have a link?

I have full LED tail's as well. Check out my thread on them. Mine don't have the upper part LED..which I like. And NO error messages.

yes this is very nice and different and very good quality, follow this link on Ebay:

ABOUT THE COMPUTER ERROR MESSAGE(REAR RIGHT SIDE MARKER LAMP)on LED tail light:
Today I install the resistor for right tail light and the error message is clear

also the rear fog lights are leds???
