For the 2021 Kia Stinger, headlight bulb fitment depends on the factory headlight type. Models with halogen headlights use a 9005 bulb for both the low beam and high beam. Models with LED headlights use integrated LED lighting for both functions rather than a replaceable 9005 bulb.
The front and rear turn signals also vary with the headlight configuration: halogen-equipped vehicles use 7507 bulbs, while LED-headlight versions use LED lighting. The reverse lights use 921 bulbs. The brake lights, center stop light, daytime running lights, license plate lights, parking lights, tail lights, dome light, map lights, trunk light, and vanity lights are LED.
For the interior, the glove box uses a 6418 bulb. Confirm whether your Stinger has halogen or LED headlights before ordering headlight or turn-signal replacements, since these configurations use different bulb types.
