Installation Notes and Tips

Confirm left-side placement before installation and compare the connector layout, bulb positions, and mounting points to the original unit. Transfer any vehicle-specific aiming or adjustment settings after installation, and test low beam, high beam, turn signal, and side marker operation before returning the vehicle to service.
