I followed Chris344's awesome DIY instructions last night and installed the Nightvision H7 HID lights from Retro Solutions LLC. They were $89.99 shipped. Honestly, I would have bought from Direct Connection Tuning, but they are currently "disabled" by PayPal and unable to receive orders.
NightVision H7
I bought the 35w kit and it installed super easy. Took less than an hour, all together, including my inept first attempts to get the headlights out (forgot exactly how they worked... again). Got the lights in, started up, and worked the first time. Very nice setup, with a lifetime warranty on bulbs & ballast. Retro Solutions seems well respected, and their guy Todd was super helpful. A highly recommended upgrade.
Cutoff on the bulbs was perfect, and I felt better going 35w on an aftermarket kit than 55w. In any event, a great option.
One last thing, Chris344's instructions were right on for the wiring colors and matchup, too (just FYI for anyone that tries this with the Retro Solutions kit).
