both in blue, 2 tubes for the front (under dash)
2 tubes for the rear seats (under the front seats)

Looks pretty nice. Get some pictures when they are installed and tell us how you like them. I had the lights in my mountaineer but have yet to put them in my F150. I had a different brand, but I like the ones you got..
