  DIY - LED licence plate lights and door entrance lights

Since the ECU is monitoring the current of any exterior light, changing to a LED bulb will trigger the error message.

In order to avoid the error message, you will need to fool the ECU that you are using the correct power consumption.

This is what I used in my LED...

Yes, this is the one....they come in many different resistance value.

Is the exact one? Because I can not find a 220ohm 25w wirewound.

the one speced here says ".01 ohm 1% DALE"

I didn't realize searching for the resistor you speced was going to be so difficult.

Hi guys,

It doesn't really matter if it is 3 or 4 resistors. In my case, I just need a resister value from 80 ohms to 100ohms to be parrallel to the LED bulbs. Therefore, I put in 3 resisters of 220ohm in parallel.

For different numbers (or type) of LEDs, you might need a different resister value. You may have to do some caluculations......or just buy a few resister of different value to test.

Hope this helps.

ok... i know very little about resistors or wiring or anything like that... i do know the warning lights are driving me crazy. im going to try this licenseplate mod. i also have leds in my reverse lights. are they recognized by the ecu? if so can i add these wires to the parking lights with the license plate wires or is this too many connections. i want to remove all warning lights asap. my trunk is preped and ready to go sooo someone tell me what to do please

Nice write-up! I think i'm going to end up swapping out the license plate lights for LEDs, they look great.

you don't need resister for LED license light.

works for both E90 and E92. No warning light.

There will be error for the first few seconds if the temperature is low. RikuE90 and I have been running this Luxor setup for more than 6 months now. During the winter time, the error warning will come on for a second or 2 and it will go away but it doesn't happen during the summer time
