Finally I removed headlight and killed condensation.
I'm perplexed by the condensation problem on my rx400h 2008 for 2 monthes. I searched the clublexus.com for countless times for the way to solve the problem. I booked a used headlight assembly on ebay, that is still on the way of shipment. I had been thinking of booking a labor to replace the headlight, but finally I decided to try DIY. Here's the procedure I did.
You may know 4 bolts on the headlight assembly. 1 side, 2 top, 1 behind the light, under the fuse box. That's easy. Use your hexagon driver, 10mm. Pull forward forcefully. But remember there're connectors behind the assembly! You will find several connectors to the assembly.
Now you have the whole headlight assembly off the car. You can use hair dryer to blow through high beam bulb hole, letting the hot air go out through low beam bulb hole. Of course you need to remove the cap covering low beam bulb. 10 mins, the condensation went out.
hot air in.
Hello
Glad that you fixed the problem make sure you buy a sealant to reseal the headlight housing to make sure no more water goes inside you can buy the sealant at homedepo or autozone.
So my right headlight had water condensation and the ballast went bad. I ordered a new ballast and installed it. Its actually just hanging inside the engine because the screws on the ballast cover had rotted and I had to break the cover off. It seems like I will have to order a new headlight because the UV coating has failed on it also. I would just seal it all up with waterproof silicone.
I think your car could have been eligible under Lexus warranty to replace headlight assemblies if they show condensation.

Your link to Lexus spells it out. I had both of mine done in Feb. 2016 on my 2007 RX 400h two monthis before the end of the secondary warranty expiration (i.e., nine years after first use/sale). Thank you Lexus of Clearwater, Fl.!
