There seems to be nothing on line about the Visions. I did a test drive of the Vision Tour last weekend and noticed here were 3 distinct lamps on the front of a Vision. One is centered and on the bottom of the cluster and the other two are larger and above and to both sides of that center one. What is each one and when is it turned on? Is one or more a high beam only? Are any of them any more than typical headlights in terms of bulb type?
