For the 2011 Hyundai Genesis, the low-beam bulb depends on the headlight system. Models with halogen headlights use an H11 bulb, while models equipped with HID headlights use a D1S bulb. The supplied fitment data does not list a separate high-beam bulb, so confirm the headlight assembly before ordering.
Other notable exterior fitments include 2357A bulbs for the front turn signals and parking lights, 168NA for the front side markers, and 7507 for the rear turn signals. The reverse lights use 921 bulbs. The brake lights, center stop light, tail lights, and rear side markers are listed as LED.
For convenience and interior lighting, 6418 is used for the license plate, courtesy, glove-box, and trunk lights. The dome light uses DE3022, while the interior lighting is listed with 168 and 917 bulbs. Match the replacement to the original headlight type and lamp assembly.
