Honestly, at first I was under the impression that if it was dark outside (determined by the light sensor), even if your lights are off, if you pull the stalk towards you to "flash" the high-beams, the Xenons flashed as well....that makes a little bit of sense. But then I got pissed the other day when I pointed the car one of the house windows (for the reflection) and did the "flash" only to see the Xenons flashing as well!!
I've been dealing with Infiniti Consumer Affairs lately to get my stupid chattery wiper fixed...next time I get on the phone with them, I will also ask why the lights are setup this way.

Dragon, the yellow turn signals and clearance strip actually work for me. My Coupe is Black and my NJ license plate is yellow, as are the clearance strips and the turn signals, and the Brembos are somewhat yellow. Gives my car a little black and yellow theme to it... =P

wickedik, you obviously know absolutely nothing about Xenon headlights so keep your poor advice to yourself, kthxbye.

Anyways, just to conclude the topic and put everybody's minds at ease (since I started this whole thing): Infiniti Consumer Affairs called me back today about my chattery wiper problem...gonna get it fixed as soon as I can take it to the dealership.
But as for the headlights flashing with the high-beams when the headlights are off, I asked the rep about this. He said that he has spoken with the engineers about it and the bulbs suffer no performance or lifespan loss when they "flash" like that. He could not speak for Xenon headlights in general, but as for all G35 models, he clearly said it causes no negative effects to the Xenon bulbs when they flash on and off.
Take the advice as you want, I'm just relaying what the representative told me.

Thanks,

The average Xenon bulb lasts for around 3,000 hours of usage. Of course, its performance decreases with time. After 2,000 hours of usage, the bulbs only emit 70% illuminataion (measured in lumens) of its original brightness.
Typically, turning your Xenons on and off without giving them proper time to cool down shortens the lifespan of the bulbs. Now WHY the rep told me that "flashing" the bulbs has absolutely no effect on the lifespan of the bulb (speaking only for the G35) is beyond me, but that's what he said.
I'm sorry if the topic is too lame for you, just don't post if it is.
