2011 F250 auto headlight behavior

Hi everyone. I added auto headlights to my xlt and i have a behaviour question.
If someone could check the operation of the headlights i would be very appreciative.

First
In the dark. Turn your headlights to the auto position and hold a flashlight over the daylight sensor. Obviously they turn off. Remove the flashlight and time how long it takes before your headlights turn back on. My truck is approximately 15 seconds.

Second
Still in the dark, turn your headlights on the "manually on option". Repeat holding the flashlight over the light sensor. Do your instrument lights turn off and your headlights stay on? After i remove the flashlight it takes 15 seconds before my dashboard lights up again.

I think this is wrong but i dont have anything to confirm my suspision.

Any help would be great as i likely have to go back to the dealership a third time for this

Thanks everyone!

I haven't gone out to my truck, but that doesn't sound too unusual to me.

If I'm going through a tunnel or park in the shade, it takes maybe 10-15 seconds for the lights to come on.

When I turn on the wipers, they also take time to come on.

As long as yours are working, I wouldn't be too worried about them taking a few seconds to click on.

Thanks for the replies guys. The one i have the hardest time with is when i turn to manual setting i would have thought that the diming of dashboard wouldnt happen. Thats the one that bothers me the most.

Good luch weathering the storm. If you happen to think about it next time an opportunity presents itself let me know if your manual on mode keeps the dashboard on or not.

Thanks again

I'll try to check tomorrow night.

Sorry, no ice storm here, I'm just too tired to walk outside after lifting legs today.

I added the fog light/sensor/auto headlight switch on my 2012 F350 and noticed the same thing. Dash lights dim based on sensor reading- in (auto or on) setting of switch

Don't know if the dealership can change it. My dealership got mine working, on auto, the second try.

There was a thread a few months ago about this situation where you can't see you dash going through tunnels etc. Will try to find it and link it when I have more time.

Find it a slight annoyance, but not too bad
