What side is out?
The drivers side you just have to remove the air box assembly and you have access.
The passenger side is the pain in the ass. Turn the wheel all the way left. Remove the little plastic pop rivet things. Fold the wheel liner back, you can use the wheel to wedge it there. Remove the dust cap. The difficult part for me was removing the locking collar. I had to use an "18 flat head with a rubber mallet to knock it loose. Then you just remove the little cord that looks like a USB (it's not) and remove the bulb. Then you have to put the locking collar back on.
It's not fun, I ended up with like 6,000 little cuts all over my hand. You'll be laying on your back looking up and doing a lot of feeling around on your own without being able to see. I have larger hands so it made it even worse. A coworker with smaller hands didn't everything from above. Most people that DIY it do it the way I mentioned. Still better than $300+ at the dealer.
