Open the hood. There are three hex head bolts that hold each headlamp to the van. Remove each bolt and gently pull headlamp out from grill using the small handle-like grip. The headlamp will remain connected to the van with the lightbulb socket. Twist the collar away from the bulb then pull the bulb assembly out of the headlamp. Replace bulbs and reassemble components.
