If I get the extra money, I may go for the Diamond Stars. I'm not going for HID, that's just over kill and I'm sure the police will be all over that like white on rice.  
I am going to upgrade my wiring to my headlights however.  I was looking on this website.. can't remember the exact website at the moment... from Daniel Stern about how much lighting is effected by voltage drop.  Even for stockers.  That's why I was asking if you went for the upgrade.  I personally have my doubts about the current system being efficient.
