What is this LED for?

In a 2001 Sport Caravan on the overhead console there is a green led pointing downward,it does'nt seem's to illuminate nothing in particle,any one knows what is it there for? I've ask 2 local dealer they don't know!

I know on my Max I installed a LED and pointed it down at the shifter. It only lights up enough to make the gear letters just a bit more visible. Cover your does it make anything brighter or easier to see?

Opening and closing of the power doors/liftgate??

It's not to lite up anything,if i put my hand over it i still see every controls,it's not a switch, just a plain Green led???
