Problem with lights

[Dando]

So odd problem with my lights. If I have my lights on and shut the truck off as soon as the ignition is off it will no longer matter if I shut the lights off with the switch the headlights only still remain on. If I turn them off before turning off the ignition they are off like you would expect. Sometimes the rear tailights do this too, the rear is very intermittent but the headlights do this everytime I try. What is going on here? Luckily I put LEDs in the rear of my truck because I didn't notice it that it did this last night and I am sooo proud of the truck for having lights on all night and still starting at -4*F this am.

I believe there is a sentinel relay under the dash that keeps the lights on for a short while as how you are describing . You can unplug it and everything will work as normal . Try turning the key of before the lights and then turn the lights off and wait to see if the lights go off in a couple minutes .

There is a delay feature for the lights. This allows you to get in the house at night and see your way in.

Thanks, I'm going to go out a try turning on ignition and lights to test for sentinel. Now if I have this feature and I don't want it to be active I can just unplug the relay (once I locate it) and this will make the lights work as if the feature didn't exist?

...or just turn off the lights before shutting off the engine.

It's a module and looks like this:
