I'm looking to put DDM 35W 8K HIDs in my wife's 2005 Grand Prix SE. I'm going to do the lows, highs, and fogs. I have a couple of questions.

1) I want bright lights because hers are dim, but I would like a light blue tint to them, I don't want to put in 55W because of the high temp, would anyone recommend a different color like 6K?

2) Do I need anything else other than the kit? Like the error eliminator?

3) Also, how hard was the installation?

Thank you in advance for your help.
