Bumper Impact Molding Lights
I have a euro front bumper and bumper impact molding doesnt have cutouts for the side marker lights. So I was wondering what to do with the light sockets so I dont get a message and or could I still use them?

1) Ohm's Law; The mathematical relationship between voltage, amperage, and resistance. The voltage is 12v, you can get the amps by reading what the wattage of the bulb. Calculate the resistance. The current is equal to the voltage divided by the resistance. Watts equal to the voltage multiplied by the current.
2) With the bulb in, measure the amps in the circuit and calculate the resistance.
3) With a meter, measure the resistance of the bulb.
Resistors have metal leads that you can bend over and stick in the socket.

Side marker also using 5W bulb, hence our all time favorite 100 ohm 10W radioshack resistor will work perfectly. (enough resistance to "fool" the w210)

But how do I plug it in? Just cut the socket and go directly onto the wires?

I have burnout "4 LED" inside the "8-LED festoon".
I found those 8-LED festoon not very reliable.
Take a good look inside the 8-LED bulb ( no resistor ), so my theory is that...if it is 8-LED, it must using parallel connection within the bulb. It will NOT be possible to light up 8LED serial connected w/ 12V spec.
Say, your car provide 12V, yet it frautuate between 11V to 18V.
3mm LED usually Max out at 3.3V and reach max brightness around 2.7V Such 4X3.3V =13.2V (MAX)
However, if the voltage frautuate in your car may cause excessive current to pass the LED without "resistor to protect them" that caused burn out.
On the 6 LED festoon, serial connection is possible.
at 6X3.3v=19.8V(Max) so...even the car provide only constant 12V, these 6-LED bulb able to reach its 80% brightness.
And the 100 ohm resistant we connected via parallel style really has NOTHING to do w/ the function has the LED bulb w/ put in.

I think you have explained why mine has been burining out...yes, mostly 4 out of the 8 LEDs burnout, in one case all except one burnt out
And the burnouts occur mostly on one particular side. For a moment I thought my car was putting out irregular and sometimes excessive currents, from what you say that is normal a normal thing? I have burnt out 6 bulbs since I embarked on the experiment...
I have been told my latest 8-LED bulbs are "improved" and bighter versions - which seem to be the case. Haven't burnt anyout so far...touch wood! And they do seem a little brighter than the old ones.
So, what do you think? A lower Ohmmage resistor is required to fool the computer where a bulb is not in place?
Perhaps you might want to experiment with your licence plate bulbs..if you take out one of the bulbs, does your bulb-out warning pop up on your dash? In the case of the licence bulbs, I think it is good that my car will still tell me the LEDs have burntout...I hope not too often...
