The 2021 Hyundai Elantra’s headlight bulb type depends on the trim and whether the car uses halogen or LED headlights. If your model has halogen headlights, you’ll replace individual bulbs; if it has LED headlights, the headlight assembly is typically serviced as a unit. Always verify the exact bulb codes in your owner's manual or on the door jamb label for your vehicle.
Two headlight systems offered on the 2021 Elantra
The 2021 Elantra can come with halogen headlights on lower trims or LED headlights on higher trims or with certain packages. The replacement approach and bulb codes vary with the system your car uses.
Halogen headlights: common bulb types
If your Elantra uses halogen headlights, these are the most common bulb types for replacements. Note that exact codes can vary by trim and production date, so always verify on the bulb itself or in the manual.
- Low-beam bulb: typically H11
- High-beam bulb: typically 9005 (HB5)
- Fog-light bulb: commonly H11 on many trims, though some configurations use H9 or H16
Halogen systems require you to replace the bulbs individually when they burn out, which is common for Elantras with halogen headlights.
LED headlights: what to know
Vehicles equipped with LED headlights do not use standard replaceable bulbs. If an LED element fails, replacement usually involves the entire LED module or headlight assembly, and service can be more involved or require a dealer or specialist shop.
How to determine which system yours has
Use these steps to confirm the correct bulb type for your specific Elantra:
- Check the owner’s manual section on headlights and bulbs.
- Inspect the bulb currently installed by removing the headlight access cover or removing the bulb itself, if you’re comfortable and it’s safe to do so.
- Look at the sticker on the driver’s door jamb that lists bulb types for your vehicle’s configuration.
- Use Hyundai’s official parts lookup with your VIN or contact a Hyundai dealer for the exact bulb code.
With the exact system identified, you can select the appropriate replacement and avoid incorrect purchases.
What to buy if you’re replacing halogen bulbs
For halogen Elantras, purchase the specified low-beam and high-beam bulbs or any other required bulbs (fog lights, daytime running lights) according to your vehicle’s configuration. Here are the common halogen options linked to the typical Elantra setup, but verify first to avoid errors.
- Low-beam: H11
- High-beam: 9005
- Fog light: H11 (if equipped with fogs)
Always confirm the exact bulb code for your vehicle before buying, as some model years or trims may vary.
Summary
The 2021 Hyundai Elantra can use either halogen or LED headlights, depending on trim. Halogen systems typically use replaceable H11 low-beams and 9005 high-beams, with possible H11 fog lights; LED systems use non-replaceable LED modules. Check your owner’s manual, the door jamb label, or Hyundai’s parts lookup by VIN to confirm the precise bulb type for your car.
