Installation Notes and Tips

Verify left-side fitment before installation and confirm the vehicle matches the listed year, make, and model. Inspect the mounting points, electrical connector, and aiming after installation to ensure the headlight is seated correctly and aligned for road use. Because this assembly uses halogen bulb technology, confirm the vehicle’s lighting system is set up for the specified application before final assembly.
