The top one is the optional HID headlight system. The bottom is the standard halogen lights.

Here is a third version. This is from the 2012 450H with Ultra Premium II and LED headlights.

I knew about the 3rd headlamp and I like that better but I guess it's from hybrids only. Thanks for the info fellas.

I wish it was reversed for the halogen and hid. I prefer the headlamps on the outside.

yeah I dont know why Lexus went through the trouble of creating two different housings for headlights, three if you count LED. I speculate it might have to do with bulb height and not shining light into other people's eyes

Majority of other makers as well. Perhaps motors for adaptive headlights?

With the Bi-xenon HID's there is technically only one beam. For low-beam there is a shutter that covers part of the light source.

It's not a light that can stand constant on/off required when a 'normal' high beam comes on such as in halogen bulbs. On the LED's it's a halogen bulb for high beam.

So on the standard halogen low beam and fogs, if I changed to HIDs, will the housing handle to higher UV emission? Even if I use the phillips bulb?

Correct but also available in France since 2009- 2010, when the RX 450h was available but with a given package called "president", with the two leds, xenon, and active/adaptative and not only in 2012

See my car pictures attached (2010)
