I have to disagree. I had the HID's in my 04 and it was a bit too much of a compromise to have only low beams in the truck. The quality also seems to just be too damn spotty to really be considered 'worth it'. Even with the relay kit on mine, there were times where only one bulb would ignite and i would have to click back and forth until both would turn on.
I hated having only low beams as well. In order to do it right, you should buy the hi/low kit with a relay harness. At that level you would more than likely be at about $100. Then you still have the glare issue. I hated pulling behind a Suburban or something like that because i knew my lights shining directly at the back of that truck were gonna reflect right back at me and it was bright enough to give me headaches a few times. Yes my lights were re aimed after i got the kit.
I just think that most people that have them learn to live with the compromises or just don't really think that the little issues with them (lights not igniting all the time etc) are worth reporting.
I would do HID's again, but ill wait for a better aftermarket projector and a better quality kit to come out for it.
