Mine does have a headlight on buzzer... however it does not work if the headlights are left in the AUTO setting. With this setting enabled, the lights are automatically switched off when the driver's door is opened... assuming that the engine already has been switched off.

Mine is an RX350 2010 model.

Is this an import series III?

Yes, US RX350, 3rd generation.

Any idea what the option is called? One dealer is saying it is not available, while another dealer (who is too far to help me) is saying that it is part of CBEST, called Light Remind.

I think it works exactly right

I personally want the lights to stay on until I get out. In fact some times would be nice for them to stay on for a few mins longer.

My problem is that due to my strange garage layout/size I actually get out the passenger door so they dont turn off then:)

Thanks for the reply Steve.

I think you may have missed my point: the lights, when set to auto, don't ever go out (until the Battery is flat ) even if I open and close the door and lock the car. Even in the most basic car there's usually a reminder buzzer that the lights are on when the key is taken out of the ignition or there is some time delay after locking the car before the lights are extinguished automatically. The 400h seems to have a deficiency in both departments, unless I'm mistaken or missing something. For a car with a 'fragile' 12V Battery, inadvertently draining charge by allowing the lights to remain on seems to be a real shortcoming.

I know this is an old post... but does your RX have a headlight on warning buzzer? You wrote, "Even in the most basic car there's usually a reminder buzzer" < I agree, but I've not been able to confirm this.
