Because Chrysler offered different trim levels and lighting setups for the 2021 300, the bulb list can vary by market, body style, and option package. This year page organizes the available lighting positions so you can quickly identify the bulb type used in each spot and compare it with the bulb already installed in your vehicle.
For the 2021 Chrysler 300, fitment can change based on whether the car has halogen headlights or HID headlights, and some exterior lamps may be LED from the factory. That means the same model year can use different bulbs depending on trim or lighting package. If you are considering an aftermarket conversion, make sure the replacement is compatible with the housing, connector, and electrical system, especially for LED or HID-related applications. The best practice is to check the bulb currently installed in the vehicle before ordering, since the installed part is the most reliable reference when trim information is unclear.
