Hey Steve,
Yeah they are all good, look great, no troubles at all. The only things that I can think of (I'm really nit-picking) that are a bit tricky with regards to installation are:
-You have to aim the head light beam a bit lower to reduce glare to other drivers due to the increased projecting nature of the HIDs. This is detailed in the instructions, but it basically involves turning the white plastic screw on top of each head lamp a few turns, to lower the angle of the beam to where it would normally be with halogens. You don't need to do this if your car has projector Headlamps (with the lens like an SS-V)
-Screwing the new dust cover ballast cap on for the first time is a bit difficult coz it has a thick rubber seal and feels tight (but it is supposed to because its a seal)
-You might have to remove the coolant fill tube to make space to get your hand in to change the globe (pull it up and push it back when done)
You also might want to pick up a pair of LED parker lights to put in as well coz it looks silly with yellow parkers and white HIDS.
With regards to legality issues, I have had no issues with the police, been pulled up many times at night for RBT, even been complimented by the officer once for having a nice car
I went for the 6000k white HIDS, not the 8000k which are very blue, I adjusted the beams not to glare other drivers so I don't see why there should be any issues. it seems that every third car has white headlights nowadays.
