Due to availability of kits and shipping errors, I ended up with two HID kits. I replaced the low beams with Philips Stage II 6000k bulbs and ballasts. These have a slight blue tint. The bulb type is H1.
Installation required removing the light assembly and enlarging the bulb opening. This can be filed, as indicated by another member who also provided a picture. I used a Dremel tool with a stone bit to widen the opening. I also took the advice of another member to eliminate the UFO effects. I cut out 4 small metal oval tabs and glued these, using JB Weld, over the openings within the light housing (2 ovals in each light). The beam pattern is perfect. Added new wiring, straight to battery with relay and diode. Each ballast is fuse protected (15 AMP) along with the main power run (30 AMP)

The second HID upgrade consisted of replacing the H3 fog light bulbs with Philips 4100k HID lights. This was painless. No modification of the fog light assembly was required to fit the H3 capsules. 4100k is the OEM HID color for Lexus. I ran all new wiring for this option. Powered straight to the battery. Each ballast is fuse protected (15 AMP) along with the main power run (30 AMP)

Excellent author and very helpful with anything HID related!
I added a Toyota OEM fog light switch (lighted) on the dash. I removed one of the plastic plugs next to the side view mirror adjustment controls. I had to enlarge the opening slightly to get the switch to fit. I purchased the switch for about $18 from a Toyota dealer. More info can be found at:
