the way I did mine: I didn't want to mess with the actual light housing so I modified the 9005 bulb. Take out your 9006 and compare it to the new 9005. You should notice the differences in the notches. I don't have a dremel so what I did is took an old disposable butter knife and put it on a hot stove. Then just slice away at the new 9005 bulb until u get it about right. Make sure u look inside the plug couse there is a diff there as well. Just slide the knife in and it should cut off the ridges. Its really easy, just don't touch the actual bulb and if you do clean it off really well.

Oh at the end just plug in the 9005 to the 9006 slot. You might need to re allign your lights or might not. Just look at where they are shining.
