I leave mine turned off. It is a PITA, a match burning in the next county will turn them off. It is 2000 feet to my house from the main road and I have to hold the high beams manually because the auto doesn't work below 20 mph.

 

Works well for me.

 

I like them and use them everday

 

Remember everyone; you can have the dealership change the sensitivity of the intelligent highbeam system.

This is one of 16 features that you CAN'T change on your own (even with the nav system personalized settings menu).

See the actual PDF of the features, downloaded from Lexus.com, on the string subject concerning rear gate auto activation.

the standard setting is "sensitive"; you can have it changed to very insensitive.

trial this, and let us know how it works for you.

 

Cronin, I'm up in Canada and I'm in a debate about these settings. He claims the US list is different, but I believe otherwise. Can you post a link to the PDF, as we cannot subscribe to Lexus.com's user website using our VINs.

Thanks!

 

Johnny, here is the list of customizable features for the 450h. Shouldn't be different than the one for the 350.

 

Thanks Anita... I had a feeling you'd come through!

 

I couldn't find this in the hard copy manual that came with the car, is it in the on-line manual? What would be a good search term or phrase?

Thanks,

 

After I posted that, I went looking myself and couldn't find it. But I did remember where I saw it. And now it's not there as it isn't an option anymore. It was one of the video's on the Lexus site that showed how stuff works. I may have downloaded it onto another computer though and if I find it, I'll send it to you. **I just found it online and it's changed, but that's where it was I'm sure** And online it still shows as an option for the RX.

If you turn your lights on w/o the intelligent high beam at night and get down near the lights while someone else works them, you should see/hear the shutter. And note there is only 'one' bulb available VS a high beam and low beam bulb.

 

My apologies for posting this link from a BMW forum, but it does explain how Bi-Xenon headlights work (yes, it's a shutter mechanism, in most cases). Note also that the "headlight flash" function (pulling the headlight stalk toward you) results in flashing the halogen lights (unless the HID low-beam headlights are already on.) This is necessitated by the lengthy time it takes for an HID lamp to reach full brightness from "off".

Thanks for the post, I was beginning to think I fantasized the shutter while looking in an 'empty' wine bottle . Anyway here is the actual video (from your board) of the shutter working. http://forums.bimmerforums.com/forum...6&postcount=14

 

Thanks Cruiter and BCRCornet a very informative thread. I had read about lamps with magnetic bases and a solenoid moved the lamp in and out of the reflector to vary brightness.

Thanks again.

 

Quite right, though the "shutter" method seems more efficient, to my way of thinking.

BTW, the brightness of the actual HID bulb doesn't vary - rather, the beam pattern is changed between "low" and "high" beam. Moving the bulb or actuating the shutter just removes the cutoff from the beam: voilą! - high beam!

 

I just picked up my RX350. According to the window sticker (which should be accurate, yes?) it does have intelligent high beams. Since I haven't driven with the lights on yet I can't tell. Are they really there?

 

Uh, that's kinda hard for us to answer, you have the car , but I guess it will depend on the build date. It seems in their infinate wisdom, Lexus has removed the intelligent high beam function.

There are folks that did not like them complaining about street signs, fences, etc constantly causing the 'dim' function. And others such as myself that like them. On the open road they actually work really well (as far as I'm concerned) but then again, that's just an opinion.

You'll have to put your lights in the 'auto' position with the stalk in the forward 'high beam' position and drive at night to tell. There is a lot of technology and new features built into your car, you should really spend some time studying the manual on the issues you're concerned with.
