I've ordered these: Amazon.com: 2 Sets 4PC of 4x6 H4651/H4652/H4656/H4666 Projector Headlights + 6000K White H4-2 Single Xenon Slim HID: Automotive
and these: Amazon.com: Innovited AC 55W HID Xenon Conversion Kit With "Slim" ballast - H4-3 9003 - 6000K Bi xenon HI/LO HID - 2 Bulbs & 2 Ballasts: Automotive
and will have my local aftermarket car guy install them next week. He is already familiar with these Toyota electrical systems (i.e. polarity issues, upgraded harness, bla bla bla...) I'll post pictures of before and after with night shots so I/we can compare the light output difference. The Maxxima LEDs were just too expensive for me to stomach at $160 PER light... I will be out right around $350 installed on a light set-up that I can always swap bulbs should I ever want to change due to wear or color temperature.
I'll be curious about how those are when you get them installed. I'm in desperate need of upgrading my lights as well.
