Installation Notes and Tips

Confirm the existing bulb type, base style, and headlamp configuration before installation. This bulb is listed for high beam, low beam, and combined high/low beam positions depending on the vehicle, so match the fitment row to your exact year, make, model, and lamp package. For example, it fits 2019-2020 Hyundai Accent, high beam and low beam, and fits 2014-2018 Toyota Tundra, high beam and low beam. It also fits 2006-2020 Honda Fit, high beam and low beam. Avoid using this bulb in vehicles equipped with LED or HID headlamps when the fitment notes exclude those systems.
