For most 2018 Chrysler 300 models with halogen headlights, you’ll need H11 bulbs for the low beams and 9005 bulbs for the high beams; the fog lights typically use H11 as well. If your car is equipped with HID or LED headlights, the bulb types are different and may not be replaceable in the same way. Always confirm with your owner’s manual or the label on the headlight assembly.
This article explains the common configurations you might encounter on a 2018 Chrysler 300, how to identify which setup your car has, and how to verify the exact bulb type for your specific trim and options. The goal is to help you avoid buying the wrong bulb and to outline where to look for the correct specification.
Common headlight configurations on the 2018 Chrysler 300
Halogen headlights (typical on lower trims)
Most 2018 Chrysler 300 models with standard halogen headlights use a few well-established bulb types:
- Low beam bulbs: H11
- High beam bulbs: 9005 (HB5)
- Fog lights: H11
In halogen-only configurations, these bulb types cover the primary forward lighting needs. Always verify with the owner’s manual if you’re unsure about your specific build.
High-intensity discharge (HID) headlights
Some 2018 Chrysler 300 trims offer HID headlights, which use a different bulb technology and may alter the exact bulb base you need. The exact bulb type can vary by the headlamp assembly, so verification is important.
- Low beam bulbs: D2S or D3S (depends on the exact HID headlight assembly)
- High beam bulbs: Often HID as well (or a separate bulb depending on the system)
- Fog lights: H11 (if the vehicle is equipped with fog lamps)
HID systems require matching ballast and bulb types; replacing “like-for-like” halogen bulbs will not work in HID setups.
How to verify the exact bulb for your car
To ensure you buy the correct bulbs for your exact vehicle configuration, follow these steps:
- Check the owner's manual for the bulb specification listed for your trim and headlights.
- Inspect the headlight housing label or connector; some vehicles have a bulb type printed on a sticker near the back of the assembly.
- Identify whether your trim is equipped with halogen, HID, or LED headlights via window stickers, dealership documentation, or the vehicle’s option code.
- If in doubt, provide your VIN to a Chrysler dealer or reliable parts retailer to confirm the exact bulb base and wattage.
Using the exact bulb type prevents fitment issues and ensures proper illumination and safety.
Summary
In short, most 2018 Chrysler 300 models with halogen headlights use H11 for low beams, 9005 for high beams, and H11 for fog lights. If your car has HID headlights, the low and high beam bulbs are typically D2S or D3S (depending on the assembly), and fog lights, if present, are usually H11. Always verify against the owner’s manual, the headlight label, or your vehicle’s VIN if you’re unsure of your specific configuration.
