For the 2010 Chrysler 300, the high-beam and daytime-running-light bulb is 9005. Low-beam fitment depends on the model and headlight system:
- C SRT8 with halogen headlights: 9006XS low beam.
- C SRT8 with HID headlights: D1S low beam.
- Limited: 9006 low beam.
Check the vehicle configuration and headlight type before ordering, especially on the C SRT8, where halogen and HID systems use different low-beam bulbs. Other notable fitments include 3057 reverse lights, 3057R brake and tail lights, and an LED center stop light. Front and rear turn-signal bulbs also vary: the C SRT8 uses 3157A front and 3757A rear, while the Limited uses 3157 front and 3057 rear. License-plate and front side-marker applications may use either 2825 or 98. Interior fitments include 578 for the dome and map lights, while courtesy-light fitment should be compared with the original bulb before replacement.
