Package Contents:

Before starting the installation process, ensure your package contains the following items:

If your vehicle is equipped with non-OEM turn signals, you may experience hyper flash or problems with the sequential signal setting on these headlights due to unmatched impedance with your original vehicle settings. This is not a defect in the headlight.
