Guys here is some clarification on how the Autolights work on the T4R and many toyotas. My 4th gen does this also.

the following scenario needs to happen
-drive truck
-park
-headlight switch in on position before turning off vehicle
-turn off vehicle
-**exit vehicle
-this starts the countdown timer of 30/60/90 seconds
-headlights will turn off after you close the door
-pressing lock 2x in many toyotas will turn off the headlight.

Why would the headlights stay on? Under what scenario?

1: if you remote started the vehicle and it shut off on its own. if the headlights are in the on position. it never saw the door open to start teh countdown timer.
2: if you open the window and reach in and turn on the headlights and never open the door. it will never go into the countdown timer mode.
3: in you shut the vehicle off and never got out of the vehicle, the headlights will stay on because it never "saw" the door open to start the coundown timer to turn off the headlights.

I hope this makes sense to everyone.

Now with the new remote starters i sell, it takes car of this very issue with the 100% plug and play kits.
