Glare Free Headlights enabled with Forscan, but no difference?

[Shmoe]

I probably wasn't clear... they won't go back to full-on bright until 25mph, which may or may not be part of the anti-glare itself now that I think about. I'm presuming that the anti-glare functionality works at the same speed, though, since it would be silly to have them remain at full brightness for 5-10mph regardless of oncoming traffic.

It's part of the auto high beams.. the manual mentions they are off under 25mph as well.

"Glare-free headlights: enhances Auto High Beam behavior to provide localized dimming of brights based on surrounding traffic..."

Thanks for the reminder of what this function is supposed to do. I now recall it was something I would never use so dismissed it. I NEVER use auto high beams as in my opinion every vehicle I have ever driven with that feature leaves the high beams on FAR longer than they should be when there is approaching traffic. This is particularly true with modern (far brighter) headlights.
And yes, the vehicle code lets you get way too close before requiring you to dim the lights too.

Small snippet from the Operational Guide I posted based on Canadian Owner's Manual:

The system turns on if all of the following occur:

• The ambient light level is low enough.
• Your vehicle speed is greater than approximately 52 km/h (32 mph).

The system turns off if any of the following occur:

• The vehicle speed falls below approximately 30 km/h (19 mph).

So there is a delta between on and off.

I used Forscan to enable Glare free but don't see any changes Do I have to reset modules? I verified the changes were accurate. (2025 Flash)

I missed one entry and now it works!
But my original mistake took out the steering assist.......
I downloaded the as built from Ford Service and will persevere.
I put the Change in the APIM 7DO-09-03 in the second group instead of the first group. I fixed it, but when I changed it the first time, it changed some other settings on it's own.
I'll figure it out..
Aren't computers wonderful?
It's so great to have this information and tools available. I for one appreciate this. It would be great if my eyes were younger.

Interesting... so if I'm going 25-31 MPH on a dark road and another vehicle approaches, I'm blinding them because glare-free doesn't kick in until 32 MPH but my full-on brights kicked in at 25 MPH... brilliant design that is

That's not how glare-free works. Glare-free replaces Auto High Beam, not in addition to. If you switch Glare-Free off then you are in charge of low or high and there is no automatic switching. With Glare-free on,, it starts low and only switches to glare-free high if over 32, no oncoming cars, etc. Switches back to low if you slow below 19 (or another car approaches).

And the 32 mph is from a Canadian manual. It could very well be that it's 25 mph here (or maybe Ford changed it). I've never noticed the exact speed it turns on TBH.

My response above was mainly to show that the on speed and off speed are different.

I put the Change in ... the second group instead of the first group.

If I had a nickel every time I did that, I'd have 25 cents. That's why I make backups now.

Ok, fair enough, I misunderstood what you were saying. It definitely switches on at 25 mph at full brightness on my rural road on my 2022. I'll have try and watch for when it turns off.

That is exactly the problem that it solves. It dims the part where the other car is, and just that part, plenty early, leaving the shoulders at full high beams. It's really a great feature for those of us who drive rural roads with lots of deer and moose.

Those long straight stretches where you are either following someone and would have to stay on low beams the whole time, or meeting someone that you can see coming 2 miles away and not sure when to dim? Problem solved.

Thanks for the 25 number. I’ll update my Guide post to indicate 32 may be wrong.

How far out? Really.

 

[Shmoe]

How far out? Really.

Pretty far... half mile or so you'll see pixels dimming out.

If it really is that far out, I'm impressed.
At least in most states, the vehicle code is 500 feet - which is too close even with old headlights. With modern headlights, that is FAR too close.

That was how I understood it as well.

Yes, the first thing I did was back up all the modules like the FORscan guide says to do and it came in handy.

I also made a mistake in one of the changes and reverted to what I had saved then tried again more slowly and carefully.

Reminded me of what a pain my Fortran class was back in the 1970's on an old computer system that used punched tape (like punch cards but if you make a mistake, you have to start the whole dang tape over again).

Can you believe they sell old used punched tape as 'vintage' on eBay and ETSY?!

I guess I should have saved all the ones I fudged up in that class
