Forscan - Disable DRL while lights are on

[Firn]

The lightnings lights are fantastic, but being so bring, and especially with glare free, I'm always looking for ways to reduce glare to oncoming drivers.

Functionally the DRLs (the white squares inside rhe headlight) provide zero useful lighting when it comes to driving a night, however they do contribute to glare.

I have found a few threads on adjusting drl brightness with forscan but have had no success. More specifically though I want to completely disable the white DRL while the headlights are on.

Any tips?

I thought the DTRL shut off when headlights are turned on. They do on my 2013 XLT.

I do believe the DRLs also shut off when your low beams are on at night. Forscan can be used to adjust the brightness of the light bar but am unaware if it can adjust the brightness of the DRLs.

Mine stay on, as seen in the image below. I also believe this is shown on other trucks if you go to the drl post in the forscan thread.


Unfortunately the forscan changes affect these lights, but do not appear to work for everyone.

Confirmed on my truck as well. I wonder why they changed that from my other truck. On the 2013 the DTRL only come on when you shift to any gear position other than park.

Both these statements are wrong. Forscan can adjust the DRLs and default is 10%. If you make them 100% then at night they are way too bright and drivers will flash you because it looks like you have your brights on.

Discussed and documented in the Forscan v2 thread (see my sig).

My solution is to completely disable the DRL. I am opposed to DRLs primarily because WAY too many people are driving around at night with the vehicle completely dark except the DRL. Secondary reason is there are circumstances where any white lights are unacceptable yet you may want to leave have the vehicle running (astronomy watching, viewing a light show, drive in movie, etc). For the second reason listed, I am strongly opposed to forcing headlights on as well.

The light in question, the middle section of the headlight, is not "the drl". It is a light which serves numerous functions and numerous different levels of brightness and colors. One of those functions is during the day as a DRL. It does other things at night. It is not glaring or blinding people at night. No you cannot turn it off at night.

FYI, it has been reported by two members in the Forscan v2 thread that changing the DRL to a much higher value does blind people at night (or at least piss them off as one member said). Start with this post and go up to #22.

So far I’m aware that the middle section is white DRL (adjustable) and amber turn and hazards. What other functions does it serve at night?

My solution is to completely disable the DRL.

Did you do this by changing the DRL to 0% via the mod in the Forscan v2 thread - or some other way? I would like to update that post with your findings.

It is what is considered the DRL, it is the device that Ford uses to meet the DRL requirements and it is the device that some have been able to adjust. It can be the drl AND serve other functions too.

Thats not how glare works. Every lumen put out is a lumen that contributes to glare seen by other drivers. There isnt one source of glare, its anything and everything that increases the amount of light that impacts oncoming traffic. There is already significant light put out by the driving beams, turning the DRL off REDUCES the amount of light impacting other drivers and CONTRIBUTES to reducing "glare". And no, it does not do "other things" at night, it provides no functional or legal purpose when the headlights are on.

No. There is a setting on the vehicle settings to turn DRL off. I would have to poke a bit to find it again, but it's there and not hidden.

This completely disables the DRL though, correct? No DRL in any driving conditions.

Just want to be clear for other readers as some will find it valuable, but not quite what I am looking for.

You unwillingness to accept reality will continue to result in your disappointment.
