For most 2020 Hyundai Elantras with standard halogen headlights, you typically need H11 for the low beams and 9005 for the high beams. Fog lights commonly use H11. If your car uses LED headlights, bulbs aren’t user-replaceable and you may need to replace the entire headlight assembly or use a manufacturer-approved retrofit kit.
Common bulb types for the 2020 Elantra
The exact bulb you need depends on the headlight function and the trim/market. The guide below shows the typical halogen setup used in many 2020 Elantras.
- Low beam: H11
- High beam: 9005 (HB3)
- Fog light: H11 (some markets may use different types)
Note: Some 2020 Elantra models may feature LED or HID headlamps, in which case the bulbs are not replaceable in the standard way.
How to confirm the exact bulb for your vehicle
To ensure you get the correct bulb, follow these steps:
- Check the owner’s manual bulb section for the exact specification and part numbers.
- Inspect the headlight assembly label or the back of the housing for a bulb type indication.
- Provide your VIN or trim level to an auto parts store or Hyundai dealer to verify compatibility.
With LED or HID headlights, replacement bulbs may not be available; you might need to replace the entire headlight unit or opt for a certified retrofit kit.
Upgrading options and tips
If you’re upgrading for brightness or color temperature, consider these options, keeping in mind compatibility with your headlamp housing and legal requirements:
- Halogen upgrades: Choose high-performance H11 and 9005 bulbs from reputable brands (e.g., Sylvania, Philips) that offer higher lumens while maintaining beam pattern.
- LED/HID upgrades: These require appropriate housings and possibly retrofit kits; ensure alignment and road-legal compliance.
- Professional installation: For any retrofit, especially LED/HID, consider professional installation to ensure proper aim and safety.
Bottom line: verify your exact headlamp type and trim configuration before purchasing any bulbs, and consider upgrading only within the constraints of your vehicle’s design and local regulations.
Summary
In most cases, a 2020 Hyundai Elantra with halogen headlights uses H11 for low beams, 9005 for high beams, and H11 for fog lights; LED or HID headlights may not use replaceable bulbs. Always confirm with your owner’s manual or Hyundai dealer for your specific trim and market, then purchase bulbs from a trusted brand to ensure fit and performance.
