For the 2020 Chrysler 300, headlight bulb fitment depends on the installed headlight type. Vehicles with halogen headlights use a 9005 bulb for both the low-beam and high-beam functions. Vehicles equipped with HID headlights use a D3S bulb for both low beam and high beam. Confirm whether the vehicle has halogen or HID headlights before ordering replacement bulbs.
Several other exterior lighting functions are listed as LED rather than replaceable bulb sizes:
- Fog lights: LED
- Daytime running lights and parking lights: LED
- Brake, center stop, tail, reverse, and rear turn signals: LED
- Front and rear side markers: LED
- License plate lights: LED
The supplied fitment data does not list a separate front turn-signal bulb size.
