So I got my bulbs for a little more than $5 a piece on Amazon. I went with a xacto knife and it worked like a charm. I can definitely notice the increased light output. I have just one question for you guys, did you find that the bulbs did not completely finish seating when you installed them? I mean, it's probably less than a pube hair turn left, but you can tell the difference of the H11 when turning to lock vs the H9. I don't think I'll have any problems with the bulb turning itself out, just wondering.
