For the 2014 Hyundai Genesis Coupe, the high-beam headlight uses an H7 bulb. Low-beam fitment depends on the headlight equipment: models with halogen headlights use H7, while models with HID headlights use D1S. Confirm the headlight type before ordering a low-beam replacement, since these bulbs are not interchangeable.
The fog lights use an H8 LED bulb. Other useful exterior fitments include 2357A bulbs for the front turn signals and parking lights, an 1156A for the rear turn signals, and a 921 for the reverse lights. The front side markers and license plate lights use 2825 bulbs.
Interior lighting includes a 579 map light bulb and 6418 bulbs for the glove box and trunk lights. Check the existing bulb and vehicle configuration when replacing any light, particularly the low beam, to ensure the selected bulb matches the installed housing.
