And since you wanted some pics of the light in the housing, here is a bit of a write up.
I removed the slam panel simply because I wanted to have easy access to the bulbs since these bulbs have a two piece install.
Pull the two air snorkel clips with a pry tool or flat head:
Pull the two piece clips out of the slam panel. Use a pry tool or flat head to pull up the center plug, then pry under it and pull all 9 plugs out:
Next is the two bolts holding the top of the light:
After that is three bolts on the bottom. Since mine were already removed, and I didn't want to recreate it, you'll just see the 3 bolt holes. But, if you pull the clips on the wheel well splash guard, you can access the bottom bolts which are located:
Next you want to unplug the headlight wire harness just behind the housing:
Quarter turn to remove the dust guard after you remove the whole assembly:
Once inside, there is a metal clip, DO NOT UNSCREW THE SMALL SCREWS! Just push the side of the clip with one screw in and down and it springs free. Remove the bulb, and put the collar of the new LED into the housing and close the clip. Then the LED bulb will slide into the collar and quarter turn to lock in place.
Here is the LED collar:
Here is kind of what the clip will look like if you're not familiar:
And finally the LED installed. There are two kinds of LED, one is a fan style (the one I chose) or there is a ribbon style, which has lots of metal ribbons hanging off the end. I didn't want to go this way, because I wanted to reseal the dust cap. I have since pushed the LED chip set into the housing and put the dust cap back on as these don't get intensely hot. I think part of the reason is the B9 has a very deep and large housing. Here is my bulb and the chip set in the housing:
And then it is a matter of putting it back together in reverse. Do leave out the bottom 3 bolts from the lights. Two have held my housing in place just fine.
Also, with the passenger side light out, you have enough room to do the air box silencer mod if you want. I got nervous and didn't turn the silencer enough to remove it, so I went and pulled the air box off. But there is more than enough room to pull the silencer off once the passenger light is removed.
Nicely executed. Thank you for the pictures. Something I may have to do. I have to add that to the plugs purchase.
Now, the next thing I have to go and search for is this "Air box silencer mod?"
