A friend recently got a new Subaru and it has these very cool puddle lights. I thought this was something my SMB needed. So I installed puddle lights under each of the doors on the van. Each one comes on if the door above it is open and I put them all on one master switch in case I don't want then to come on. The light is not overly bright but really helps when getting in and out of the van when parked in dark spots.
Here is the light I used;

This is the which that can shut them all down.
