Start by disconnecting the negative battery cable.
Next, remove the front bumper. Check out our dedicated removal video link above.
Once the front bumper has been removed, you can remove each headlight. There will be (3) 10mm bolts and a push pin to remove.
Disconnect the headlight after unbolting it, to fully remove it from the car.
Do the same for the other side.
Step 2: Transfer Ballasts & Bulbs
Remove the (4) T10 Torx screws from the factory ballast and disconnect them from the old headlights.
Remove both HID bulbs.
After the ballasts and bulbs are removed, transfer the wiring harnesses to the new headlights. Make sure no wires interfere with the headlight projector on the front side of the headlight.
Then transfer the ballasts and HID bulbs to the new headlights.
Step 3: Install New Headlights
Once the headlights are assembled, connect the new headlights and loosely install them to test for operation.
Reconnect the battery cable to verify all functions of the headlights.
After the lights have been tested, reverse the removal steps and reinstall the headlights and front bumper.
Adjust and aim the new headlights using our link guide above to ensure proper light beam orientation.
After this, you are good to go!
