Did you ever resolve the flickering of the vanity bulbs? I purchased (4) from V-LED and they are flickering. I heard that Lexus vehicles are CANBUS, but cannot confirm. Any insight into your solution would be greatly appreciated. Thx..

Nope... Didn't resolve... Don't really use them, but still want it solved.
I also have problems with my left reading light and rear dome light. They don't seem to stay on... Stay on for a bit, then turn off, turn back on etc.

Any update on the CAN bus deal with the RX330? I have heard mixed results.... I know that when a brake light went out, I saw a light on the dash come on, but I am not sure if this relates to all lights or just certain one's for the RX, and if indeed this even would be CAN bus technology or just something else...

Lexus does not use CANBUS on the RX for any other lights other than the brake lights, which are LED.
The problem, in general, with LEDs is that they require a constant 12V DC to operate. Unlike traditional bulbs, LEDs turn off below a certain voltage (not sure what exact voltage, but it's pretty close to 12V DC). The problem is that most cars don't always put out a constant 12V to every light in the vehicle. This is why you can sometimes get flickering and have them turn on and off cyclically. To remedy this, to my understanding (which is relatively basic, is that), LED bulb manufacturers have to use small capacitors and resistors to supply that constant potential.
So, to my basic understanding, these issues are with the bulb not being able to keep a constant voltage from what the car is supplying. Thus, to fix these issues, you would need different bulbs that can deal with the voltage inconsistencies better.
I do not not know what bulbs will work. This is the exact reason I do not bother with drop in LED bulbs, with the exception of the ones I put into my tag lights. I used Sylvannia LEDriving 194 bulbs for it. The reason I made the exception for those bulbs, is because they are from Sylvannia, which has had a good reputation for many years.

I have purchased bulbs from http://www.luceprodukt.com/ and haven't had an issue with the map light bulbs.
