Hyundai Accent (HC) (2017 - 2022) Service Manual: Light bulbs

Consult an authorized HYUNDAI dealer to replace most vehicle light bulbs. It is difficult to replace many Hyundai Accent light bulbs because other parts of the vehicle must be removed before you can get to the bulb. This is especially true when removing the headlamp assembly to access certain bulb(s), or when LED components are integrated into the lamp housing.
