I'm really not an expert, but I was just talking to tayln about the Electrosport kit. IMO, it's far better than the ebay hi/lo HID kits because those kits use a cheap halogen attached to the HID bulb (these use 2 HID bulbs), but here are 3 concerns:
1) That kit still depends on your reflectors to control your beam. You might have glare. Email the company for wall shots in a sealed beam headlight (like our 6054 for example). The last thing you want is trouble from the cops because you're blinding people.
2) Having 2 HID bulbs on simultaneously sounds pretty good (in high beam mode), but keep in mind that-that equals 70w of draw opposed to 55w from a standard halogen. I don't know if that's enough to affect your stock wiring harness. Moreso, I don't know how a 6054 will handle all that light.
3) Price. At $400, it's an expensive kit. You're probably $150 away from a Xenarc X6054 kit (2nd gen). It uses an HID low beam bulb, and an Silverstar halogen to compliment the high beam. It's also DOT approved. You're also pretty close to a DIY bi-xenon retro.
