Welcome to the forum.

The feature was discontinued on the 2013s -- when I subscribed and read through TIS in the June timeframe to see exactly what changed from the 2012s (see this post for my summary), it indicated that the supporting subsystems were also eliminated. If it could be done it would be mighty expensive -- a whole new rear view mirror with the camera, possibly a new windshield if your 2013 does not have the spot in the upper center dark area open between the sun visors for the camera to see though, and even if the wiring harnesses are there, the bigger problem is then getting it to connect into the rest of the truck's software. There is a complicating issue that Homelink moved onto the mirror with the 2013's (lots of people liked that as the buttons are backlight again), so it would somehow have to be moved back up to the ceiling console. You could certainly ask your dealer, but my take is they will say it's not possible because unless they read TIS differently than I did or something has changed in that regard, no dealer is going to want to muck with something that isn't officially supported by TIS, as they wouldn't be able to warrant it if problems arrose. Now, would some non-Lexus shop do the work? Maybe. Personally, I wouldn't let them try it on my new 2013 and take a chance of impacting the warranty on the rest of my wonderful ride.

I don't have a camera like you showed in my mirror, but I do have a thingamajig to the right of the mirror (inside the car looking out) at the top of the windshield. Would that be a camera for the auto-dimming headlight feature? I'm still trying to figure out how to use it, if I have it. I'll have to see if the stalk controls are set exactly has you showed in your excellent pictures. I thought I had it right, but the first time I started up the car at night I didn't see whatever icon you're supposed to see when the feature is turned on. I don't know what the build date of my car is. How do I figure that out?

Aptosuser, the camera is not part of the rear view mirror, it's in front of it. The easiest way to check if you have auto high beam is to push the headlight stalk forward. A light comes on the dash between the headlight and fog light lights that looks like a headlight with 'auto' underneath.

Aptosuser

If this icon is supposed to show up whenever the stalk is pushed forward and the lights are set to "auto," then I don't have it. I checked the window sticker that came with the car (the original owner saved it) and there's nothing in the list of features about auto-dimming high beams, only auto-dimming mirrors.

Here's a picture of the light I was talking about. As you can see the headlights and fog lights are on. I forget if it stays on when they're off. That tells you how much I use it, LOL! Also, I checked the print out on my 450h (no window sticker since I special ordered), 'intelligent' high beams were under optional equipment - LED Headlamps w/AFS, Intelligent High Beams and Headlamp Washer. Check the headlight description. HIDs were part of the comfort package, I'm not sure about halogens.

Aptosuser

I have HID headlights. It looks like the trick is turning on the foglights. So maybe this thingie in my windshield above and to the right side of the mirror has something to do with it? It has a big square window on the street side.

I would not dig auto dimming high beams. What if you need to flash your brights at an oncoming vehicle with high beams on. Will it work?

No the lights are allready on "high" when using auto dimming. So you can't flash unless you go back to manual mode.

In an effort to clear up some possible confusion.....

Does your RX have "rain-sensing windshield wiper?" Those are the kind that come on automatically when it starts to rain, IF you have the selector set to "auto" on the wiper stalk.

If so--and I'm betting you have this option--then that device on your windshield is the rain-sensing device for this option.

I love my auto high beam lights. Why did Lexus discontinue? Is it on other models like the GS?

Aptosuser

Yes, it has the fancy windshield wipers. Though I would've thought that the sensor for the wipers would be on the exterior side of the windshield. So it senses rain photoelectronically? In any case, I tried setting the headlights to auto and high-beam and the fog lights to "on" last night and I did not see the icon for auto-dimming where it's supposed to show up between the headlight icon and the high-beam icon, so I guess I don't have that feature and I'll just have to remember to dim the lights myself.

I started seriously wondering about this after my wife was ticketed for failing to dim her lights for an oncoming cop car (her Camry's headlights have auto on/off, but no auto-dimming feature). This was in Simi Valley, Calif., where she was visiting her daughter. The place is full of cops, both active and retired. The ticket cost us $239. I just hope it didn't add any points to her driving record and raise our future insurance premiums.

I find the auto-dimming headlights work quite well. I'm in a suburban metro area and have some winding, wooded roads that can be deer magnets at night. The auto-dimming high beams gives me a better look at them while quickly dimming when it senses an oncoming car. Along with the 'follow the road' beam, this works great for me.

My understanding is that you also have to have the green light turned on that's located below the rearview mirror. It's the same light that we're used to having turned on for autodimming. I thought I read that in the manual that that light must be turned on also. Then the stalk for the headlights must be pushed back. Of course, you won't see the "auto" indicator light up until it gets darker in the evening, I believe

I really enjoy my auto high beams, although they're a little sensitive if you live in a city that has lots of lights all around. But they're awesome out on a dark country road!

Oh, and make sure the stalk for the light controls is set to auto also!

Aptosuser

The green light has been on all along. I tried going through the procedure at night, but the auto-dimming icon did not appear. I wouldn't want to rely on this feature in actual driving if I couldn't be sure that I had it, of course.

EMSLEXUSRX

Okay. So your green light on the rear view mirror is on. I take it that the stalk that has the light controls is pushed back. Do you have the light control on the stalk also set to auto? If these three things are set, you should get the headlight icon with the word, "auto" on the Instrument panel showing up. If I'm remembering correctly, though, you will only see this "auto" icon showing up at dusk or dark when the automatic headlights come on.
