I tried that but there's multiple bulbs for the same housing. Like it says "back up light 1156" for one than right below it says "back up light P21W" is that the same bulb or is that for the inner and outer ?

The P21w is the same size as 1156, its just using 21 watts for the brake. The brake lights are below the turn signal bulbs. The bulbs under the reverse light will only come on when very hard braking and is really designed for rear fog lights as well. I coded the inner rear brake lights as rear fogs and will flash on hard braking. To achieve this you need to code for rear fog lights (must have rear fog light switch), and also brake force coded.
To be honest save your money and buy from Amazon. Get led bulbs that have projector bulb end and these are the ones I got: https://www.amazon.com/Alla-Lighting...ateway&sr=8-10 When you're ready I'll find the code to code for rear fog setup, but prerequisite is to get light switch that powers headlights, front and rear fogs. Search forum on switch for the x1. I have it but can't remember oem part number. Its a euro part not available in US market |

Sorry the front bulbs should be 7507, but you can use 1157 but will need to clip off one of the contact points on socket to fit for front.

by the way, I used 1156 amber rear signal. It gave a more yellow amber turn signal effect than standard rear, giving it a different contrast to the rear brake lights.

Awesome, I ordered it up. I decided to go all red, rear turn signals and brake lights. I want it to match. I got the Alla front amber yellow leds. And white 1156 reverse. How easy was it to pop these guys in, I havent looked yet.

To confirm, I am disabling cold and warm monitoring for front turn signals, rear turn signals, brake lights and reverse lights. Than switching all bulbs from "bulb" to "led" in Bimmercode. Code and done?

For you guys who have changed our your rear light bulbs to LED...can you confirm the following below is correct?
There's 1 bulb for the turn signal, 1 bulb for the reverse and 3 bulbs for the brake lights on each side? |
