DRL LED Bar brightness boosted using Forscan

[Nightshade]

This is kind of unrelated, but you guys seem pretty knowledgeable about the headlights. I have an XLT 302a and when I put the dial in auto, the headlights and taillights stay on as if it’s night time. I tested the light sensor and it seems to be working as it changes the radio to dark mode. Is there a forscan setting for this as well or should I just take it to the dealer?

It depends. Sometimes if it’s on auto, the sensor turns on the tails too if it gets to a certain darkness but I have to ask. Was it an overcast day or raining when this happened or full sunny?

Hello,
Do any of you know if it’s possible to keep the DRL’s ON while the vehicle shift is in parking?

Just turn the light knob to the second switch; it’ll leave the headlight led bar and tail lights on while in park.

Did this mod, What a difference!

Some shots from last night.

Have followed the thread and can not see any mention of the centre orange bar that appears to be on in the above pictures. Have just got a Canadian spec Lariat with LED headlights and in all modes the centre bar does not light. Is this something to do with it being Canadian ? Is there possibly a Forscan coding I can alter to get it to work.

Your center amber bar should light as it does from factory. My new ‘21 Lariat (finally came in and traded in from a XLT) has it on with this mod; this mod shouldn’t interfere with it at all.

Thanks. It must be something the importers did then, to get it past SVA in UK. Have not carried out the brightness modification yet. Will check first to see if there is a wire at rear of headlight that feeds the centre orange LED. If so they may have cut that as unlikely to have known coding to remove this part only in Forscan.

You’re welcome. If that’s the case; I’d rather bring it in to the dealer and tell them about it seeing it’ll be covered under warranty. I’m hoping it’s not a defect headlight as those are dirty expensive.

The amber bar on my US Lariat only comes on with my Hazard lights (and turn signals). :-(

Yeah. There are two.. the bottom one is turn signal only. The one between the two projectors is the side marker light. The bottom one won’t come on for parking lights

which amber line are you talking about? The signal one on the lower or amber line in the middle of 2 projector lenses? If it’s in the middle, it’s a steady burn and stays on but if it’s the lower one of the headlight, only turns on when you’re signalling. That’s it.

Appreciate the above interest in my initial question re centre amber light between the two LED headlights.
Without boring with UK car lighting design and regulations they have been altered to operate to conform.
White DRL lights shine bright (would have thought as per Forscan modification in this thread) together with rear red tail lights plus rear plate lights, upon engine running and putting in drive. This occurs with light switch in position O and 1 ( we call side lights you call Park lights). In position 2 (auto) they stay the same bright light if headlights are not needed.
Position 2 dark enough to turn on headlights and position 3 ( headlights on dipped or main beam). The DRL's dim to the less bright light. This addresses the possibility of causing light glare problems when driving in the dark as mentioned.
Non flashing amber lamps are not permitted in the UK hence the center bar not lighting up.

Once the vehicle has been registered, amber marker lights on American trucks do not tend to draw the attention of the authorities and are often reinstated. I will try and locate where power to the amber strips has been isolated.

Camera does not bring out the difference of DRL brightness but is very different to the eye.

Hello guys - I just wanted to report a flickering issue since doing this. Mine is a 2021 XLT. My fog light isn't flickering, but the headlight DRL's. Primarily the passenger side, but also the driver side from time to time. I'm going to reset mind tonight to regular brightness and see if the flickering goes away.

There is a very very few people that have that flickering issue, you're the 3rd/4th person so far, but is an unrelated issue to the brightness mod. It will help if you restore it back to factory settings and cycle it on and off (without starting and within 10 seconds apart of each cycle) about 3-4 times, then turn the truck on with the door closed and off, open the door until the dash has completely turned off. Re-do the change again but triple check to make sure each line is in the correct number/letter. See if that does it again.
