The 05's are one of the harder installs - mainly due to the turn-signal wart. Our kit in a one piece kit (one of our competitors uses a three piece headlight) which may make it a bit harder to install but it looks way better when it it done. Due to this we include very detailed kit specific directions with both the headlights and taillights on the 04/05's
The 06's are much easier to install - both for the headlights and for the taillights. The headlights are even easier then the bug eyes!
There should be a HID Blue on White somewhere but I can't locate which thread it might be in at the moment, sorry.
