I installed 2 recessed square lights, one over the passenger seat which swivels (the seat not the light) - it's my dining room/living room/office chair, and the second light over the head of the bed for reading in bed.
I also installed an LED strip light that has a built in dimmer switch over the kitchen counter.
I get the most use out of the kitchen light since I now use a Kindle Fire for reading and it is back lit so I don't need the overhead light.
I wish I had installed lights in the overhead storage areas, sometimes I have to grab a flashlight to find stuff in the back, particularly the front storage that holds all the kitchen equipment.
