with regards to how hard the exterior lights are to get, ( ie head lamps and signal lamps), they are very easy to access, it may take you a few minutes to figure out how the clip goes back on, but once you figured it out, it's a joke.
I have a set of CATZ galaxy white, and I turn a lot of heads, most think they are HID lamps, but they just are that clean.
PIAA may be comming out with an H1 bulb this summe/fall, but I can vouch for the CATZ at being great.
