I got these for Christmas. http://www.amazon.com/OPT7-Hea…r-Arc-Beam/dp/B00VNBEJ1G/
I finally got around to installing them a few weeks ago.

I am running Hella E-Code housings.
Installation is very simple. Remove the old bulb, insert the new assy. lock the clip, and plug it into the original connector. Hardest part was getting the clip back in to position. The difficulty will depend on your dexterity, size of your fingers, and the ambient air temp.
Here's a pic showing how much whiter these are:
It's weird to hear fans running when you turn the lights on. Won't hear them with the engine running.
Here's a quick video of driving at night:

All in all I'm happy with them.
Don't expect the cutoff you get with focused lamps, but these are much better behaved than the HID's I tried in these same housings. I did drive in the snow at dark and they were great. I couldn't see crap when I had the HIDs in.
