The change out went well - as I figured - it's never quite as simple as it seems - however, here are a couple of quick tips.
Firstly, you DON'T need to take out all of the fasteners they show in the PDF - the front 3 screws are enough to pull it down - reach in and take out the bulb. The bulb holder screws out COUNTERCLOCKWISE - they don't tell you that either. I was sure I was going to break the bulb - they are in there pretty tight from the factory.
Lastly, these bulbs are plug and play. Just changed them for the ones in there and so far appear to work just fine.
The bulb color nearly exactly matches the HIDs - so buy with confidence. No idea how they are going to last, but they look great. I'll post up pictures after it gets dark. I took a few just now, after I changed them, but you really can't tell much.
