Has anyone used one of these kits from TRS? I want to do an HID conversion, but I want to use a projector and not just a set of bulbs. These kits look like they'd be the easiest to install. It appears that theres no modification of the headlight required ( short of opening it up and putting it back together). I'm sure the output isn't as great as a full on retro, but as long as it's good I'd rather go the easier route.
Also in the link it says that there's a d2s version coming for h4 setups. What's the benefit of this, and is it a better way to go? I won't be doing this for awhile, so it'll probably be out by the time I'm ready.
