Great Topic and how-to! I believe stock lighting is insufficient and upgrading really helps with nighttime driving safety concerns.
I believe whether or not the HIDs affect oncoming drivers is all in the headlight aiming. I replaced my 2007 Silverado headlights with 55w 6000K HIDs (low and high beam) and have been extremely happy. I live in a rural area and when high beams are on, the road in front of me is lit up! The lows don't seem to bother anyone coming the other way, at least I've never been flashed.
Recently I've had to restore the headlight's surfaces due to pitting and clouding and now the lexan is like brand new. The 3M kit with the drill attachment for sanding/buffing is the BOMB.
