The 2018 Hyundai Elantra commonly uses H11 low-beam bulbs and 9005 high-beam bulbs, with H11 for fog lights where equipped. Some trims with factory HID headlights use HID bulbs such as D2S or D3S, depending on the ballast. Always verify for your exact car by checking the owner's manual or the bulb label in the engine compartment.
Across the 2018 Elantra lineup, there are variations based on trim, market, and optional packages. The most prevalent setup for standard halogen headlights features H11 for low beams and 9005 for high beams, with H11 used for fog lights on models that include fog lamps. If your vehicle is equipped with factory HID headlights, the bulbs will be HID-type (commonly D2S or D3S) and require the appropriate ballast. This article outlines the common configurations and how to confirm the specific bulb type for your car.
Common headlight bulb configurations for the 2018 Hyundai Elantra
The following configurations cover what you’ll typically encounter, depending on trim and options. Use them as a practical starting point to identify the correct bulbs.
- Halogen headlights (most common): Low beam is H11, high beam is 9005, and fog lights (if equipped) are H11.
- Factory HID headlights (less common): Low and high beams use HID bulbs (commonly D2S or D3S) with the appropriate ballast; fog lights are usually not HID and may use standard halogen bulbs.
- LED headlights (rare option for 2018 Elantra): If installed, there are no replaceable bulbs; the entire module or assembly is replaced. Check the manual or dealer for exact specifications.
Conclusion: For the bulk of 2018 Elantras, you’ll deal with H11 for low beams and 9005 for high beams; HID-equipped versions use D2S/D3S bulbs with the matching ballast. Always confirm the exact bulb type in your vehicle’s documentation or with a Hyundai dealer.
How to verify the correct bulb for your vehicle
To determine the precise bulb type for your specific 2018 Elantra, follow these steps. Configurations can vary by market and trim, and even cars that look alike may use different bulb types.
- Check the owner’s manual or the bulb information sticker under the hood, which often lists bulb sizes near the headlight assembly.
- Inspect the current bulb if accessible: read the imprint on the base (examples include “H11,” “9005,” or HID designations).
- Identify the headlight type by assembly: Halogen reflector/projector setups typically use H11 or 9005; HID assemblies require HID bulbs (D2S/D3S) and a ballast.
- Use your VIN to look up the exact bulb specification on Hyundai’s parts site or through a dealer. The VIN helps ensure you get the correct option for your car.
- Consult a dealer or automotive parts retailer if you’re unsure—bring the old bulb or your VIN to confirm compatibility.
Bottom line: verifying through the manual, the existing bulb, or a dealer ensures you order the correct bulb the first time.
Summary
For most 2018 Hyundai Elantras, the standard halogen setup uses H11 for low beams and 9005 for high beams, with H11 fog lights on models that include fog lamps. If the vehicle has factory HID headlights, you’ll encounter HID bulbs such as D2S or D3S, requiring the appropriate ballast. Always confirm the exact bulb type for your vehicle by consulting the owner’s manual, inspecting the engine-bay bulb label, or checking with a Hyundai dealer using your VIN.
