HelloCustomer my name is Mike.


You should not have to remove the headlamp assemblies, just reach behind the lamp assembly and turn the bulb. The instructions are below, please ask if you have any questions. Be sure and read the caution statements carefully.


Headlamp Bulb Replacement

Removal Procedure

    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.

  1. To remove the passenger side high beam headlamp bulb, refer to Headlamp Replacement .

    To replace all other headlamp bulbs go to step 2.

  2. Twist the headlamp bulb (3 or 4) counter clockwise until the retainer tabs are released.
  3. Pull the bulb straight out to remove.
  4. Disconnect the bulb from the wire harness.

Installation Procedure

    Notice: Avoid touching the bulb or letting the bulb come in contact with anything damp. Oil from your skin or moisture on the bulb can cause the bulb to explode when the bulb is turned on. If either comes in contact with the bulb, clean the bulb with alcohol or a suitable degreaser and wipe the bulb dry.
