For the 2021 Genesis GV80, both the low-beam and high-beam headlights use LED lighting. The supplied fitment data does not list a replaceable halogen bulb size or identify a projector/non-projector headlight variation, so verify the original lamp assembly before ordering a replacement.
The fog lights, daytime running lights, reverse lights, brake lights, center stop light, tail lights, rear turn signals, rear side markers, and license-plate lights are also listed as LED. Interior lighting is LED for the dome, map, trunk, and vanity lights.
Front lighting has the main listed variation: the front turn signal and parking light may use either a 2357A bulb or an LED setup, depending on the vehicle configuration. Check the existing socket and lamp assembly to determine which applies to your GV80. The rear lighting information does not list a replaceable bulb size for the turn signal, brake, tail, reverse, or side-marker functions; these are identified as LED.
