I installed one of the LED bulbs (passenger side) today. Install went pretty well. Here are the pics:
Here is where we start.
Lets get the intake pipe out of the way, and now we have access to the headlight bulb.
I pulled the old bulb out and shot a comparison picture.
I installed the reflector and bulb base.
Then, I had to do something about the connector. It was sticking straight up, and the plastic housing was overhanging it. So, I took it apart and rotated it. A half dozen screws on the back hold it together.
Here are some of the guts. Looks like a couple inductors, a capacitor and probably some other stuff.
Here it is all buttoned up. There wasn't a ton of extra room to get the new bulb in there, but it did fit without too much hassle. The other side will probably be a bit more tricky as the fuse / relay box is right behind the headlight.
Oh yeah, don't forget bulb grease (though I've never seen corroded headlight terminals).
