I have a 2018 GX460 premium, can automatic high beams be added? Guessing a module would need to be purchased for this to happen.

 

Different mirror....

I have the AHB mirror but wiring harness is different and also missing wire to the BCM. I may possibly need a different BCM for that option as well

IMO they are nothing to write home about. I’ve got them and keep them disabled unless I’m in an area with pretty low car density.

 

Thanks, was thinking it may be fairly straight forward to add it, but does not appear to be.

 

Not going to lie, auto-HB doesn't work well and it's not as fast, compared to my Subaru Outback.

 

Agreed, the AHB is mostly useless in my area, constantly on/off due to traffic and street light patterns.
Our old 2014 ML has better AHB function

 

I never use it, I find it flaky. Certainly not worth the expense or effort to add the feature.

 

Lexus/Toyota implementation of the AHB is really odd. It works, but not well. I have it on my 2022 GX460 and use it, but its weakness is apparent, especially when you have experience with AHB implementations that work well. We had a 2020 Porsche Cayenne S with AHB and it was flawless. And it faded the high beams on and off, not like a binary switch on the GX. Yes, this is not a well implemented feature, but I still find it useful. It is not refined like other German auto maker implementations.

 

I love the AHB on my 2022 GX but I have never had it on any other automobile before. I thought it worked well on my trip out West last year. Did nighttime driving in Dallas/Ft. Worth, Pueblo, Denver and Albuquerque. You can always use the manual method of high beam low beam, but I set my headlights on Auto and let it do its thing.

 

The sensitivity of AHB can be adjusted. I turned mine to one notch up from the default, and that seemed to get it closer to how I would use high beams manually.

How is the sensitivity adjusted?

 

On a '23, Setup/Vehicle/Vehicle Customization/Lights Settings/Headlights Auto-on Sensitivity

That setting is for the headlights auto On/Off, there is no user adjustment for sensitivity of Auto High Beam as I am aware of.

 

Ahh, you're right. I forgot which setting I adjusted, but it was the auto-on timing that I wanted to be more aggressive.
