Auto headlights?

Last night I fired up the 250 and got back out to get something I forgot and after a few seconds the headlights came on by themselves. First time that's happened. When i got back in I turned on the headlights and the light brightness did increase somewhat, tried to shut them off manually with truck running - no go. Shut the truck off after turning off lights and within a second or two they shut off.

Anyone experience anything similar?

If you have factory auto headlights it is a different position all the way counter clockwise on the headlight dial. You will also see a small black plastic bump in the center of the dash up next to the windshield that is the light sensor that is used to turn them on and off.

You could have daytime running lamps, as some trucks got them. Or it could just be a relay starting to go bad.

Is there a way to make the lights stay on longer after the ignition is shut off? Mine shut off 3 seconds after the ignition, would like atleast 30 seconds for security at my very dark workplace in a very bad part of detroit.

Yes there is by using the onboard message centre. I beleave use press the setup button 3 times and then it gives you the option of 15sec - 30sec - 60sec - 120 sec.

I don't have a set up button. I found that you have to turn this switch tweak that one, kick the tire and spit on the windshield to set it to a max of 3 minutes.

Do you have a "display message center" in your SD. If not then this was not a option installed in yours.

From what I can tell I have no auto sensor in the dash center or elsewhere. Also don't have a switch that indicates auto lights. I "did" have a 10A fuse in the power dist box for daytime running lights until yesterday. Took it out and the lights still come on after the truck has been started and running for a few seconds. Just the headlights - not the parking lights.

Beginning to think this is a weak ground issue somewhere as I went through both fuse/relay panels and my trucks manual and can find no relay associated with headlights.

Confusing for sure!

Still no success trying to find out what the cause of this problem is. Not really a problem as much as it's annoying and my not wanting the headlights ALWAYS on when driving.

I got to wondering though, could it be a short in the towing harness even though it's not being used and not directly related to the headlights? I had odd electrical issues arise in my Ranger awhile back (cruise quit working, right turn signal quit working, both sporadic work sometimes not others) and it turned out to be a problem with the under bed plug-in towing harness for my four prong tow plug. Replaced it with a new one from Rural King (similar to a farm and fleet or tractor supply) and corrected the issues.

Any suggestions would help!

Problem solved. It was an 15A inline fuse run through the auto/start system. Pulled it and walla!

I don't like the auto headlight feature or supposed "convenience." I think the system the way it is currently designed is actually a road hazard. I can't count how many times I've driven up on a vehicle in fog or low visibility where the driver is apparently unaware that the tail lights aren't working due to the auto headlights.

Our 93 T-Bird has the option but, it can be disabled on the dash and is. Worthless imho!!

Yep, that's why I never use my auto headlights. It makes it too easy to forget to turn them on yourself when it is raining/snowing/foggy/etc. I guess a lot of companies are starting to turn the lights on now with the windshield wipers so that should help, but they still probably won't come on automatically for foggy conditions.
