For the 2016 Kia Forte, the high-beam headlight uses an H1 bulb. Low-beam fitment depends on the headlight assembly: models with halogen headlights use H11, while models with HID headlights use D8S. Confirm the headlight type before ordering a low-beam replacement.
Several rear-light functions also vary with the headlight configuration. With halogen headlights, the brake and tail lights use 2357R, and the rear side markers use 2357A. With HID headlights, these applications are LED. The front turn signal uses 2357A, the rear turn signal uses 1156A, and the reverse light uses 921. Daytime running lights and parking lights are LED.
Other listed bulbs include 7506 for the center stop light, 168NA for the front side marker, and 168 or 917 for the license plate light. Interior applications are DE3175 for the dome and map lights, and 6418 for the glove-box and trunk lights.
