For the 2021 Chrysler 300, headlight bulb fitment depends on the factory headlight system. Models with halogen headlights use a 9005 bulb for both the low beam and high beam. Models equipped with HID headlights use a D3S bulb for both functions.
The fog lights are listed as LED, so they do not use a conventional replaceable bulb size in this fitment data. Other listed exterior lighting is also LED-equipped:
- Reverse, brake, center stop, daytime running, parking, and tail lights
- Front and rear side markers
- Rear turn signals
- License plate lights
Before ordering headlight replacements, confirm whether your 2021 Chrysler 300 has halogen or HID headlights. The 9005 and D3S applications are not interchangeable, and the correct choice depends on the installed headlight type.
