Caution: Halogen bulbs contain gas under pressure. Handling a bulb improperly
could cause it to shatter into flying glass fragments. To help avoid personal
  injury:
   •  Turn off the lamp switch and allow the bulb to cool before changing
the bulb.     •  Leave the lamp switch OFF until the bulb change is complete.    •  Always wear eye protection when changing a halogen bulb.    •  Handle the bulb only by its base. Avoid touching the glass.    •  Keep dirt and moisture off the bulb.    •  Properly dispose of the used bulb.    •  Keep halogen bulbs out of the reach of children. 
Important: In order to minimize the nitrogen from escaping from within the headlamp, the headlamp must be placed on a flat surface, lens down, when removing the bulb. The amount of time spent on removing the bulb from the headlamp must be kept to a minimum. If the headlamp is to be stored while repairs are being completed on the vehicle, the bulb must remain in the headlamp.
