Installing: 

Install in reverse order of removal, noting the following:

CAUTION:
  • Do not touch glass portion of HID bulb with bare hands. Even the smallest amount of moisture and/or contaminants from fingers that evaporates on the bulb during operation can cause the glass to cloud over.
  • When installing cap, ensure proper seating. Water intrusion will damage headlamp.
CAUTION:
  • HIGH VOLTAGE!
  • Danger of explosion and burning.
  • The control modules for HID lamps must never be operated (headlamps turned on) without an HID lamp.
  • HID bulbs must only be operated (headlamps turned on) when installed in the headlamp housing.
  • Never look directly at an operating HID bulb. The UV emissions of an HID bulb are approximately 2.5 times that of a comparable halogen bulb.
