For the 2017 Chrysler 300, headlight bulb fitment depends on the factory headlamp type. 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. Confirm whether your vehicle has halogen or HID assemblies before ordering, since these applications are not interchangeable.
The fog lights use integrated LED lighting. Other exterior applications listed for this model year are also LED, including the reverse, brake, center stop, daytime running, license plate, parking, front and rear side marker, tail, and rear turn signal lights.
Interior bulb fitment includes a 562 for the dome and trunk lights, a 578 for the map light, and a 2825 or 98 for the reading lights. The glove box is listed with either a 194 or 7441, so verify the existing bulb and socket configuration before replacement.
