Installation Notes and Tips

Verify sealed beam headlight configuration before ordering. Fitment varies by model year and headlight style, including some applications noted for rectangular headlights or composite-headlight exclusions. Match the vehicle year, make, and model exactly, and inspect the surrounding headlamp hardware for wear before installation. Because installation hardware is not included, reuse or source any required related components separately as needed.
