The Elantra's low-beam headlights typically use H11 bulbs, while the high-beam headlights use 9005 bulbs.
In practice, bulb types can vary by trim level, market, or optional equipment. To be certain, consult the owner's manual, check the bulb designation on the existing bulb, or inspect the headlight assembly labeling before purchasing replacements.
Bulb types by function
The following list summarizes the common configuration for the 2010 Elantra’s headlights.
- Low-beam: H11
- High-beam: 9005
These are the typical specifications you would use when shopping for replacements. Always verify with your specific vehicle to avoid buying the wrong size.
Notes by trim and region
Some regional models or specific trims may differ, especially if fog lights or aftermarket upgrades are installed. When in doubt, reference the owner’s manual or contact a Hyundai dealer for the exact bulb size for your exact vehicle configuration.
Tips for replacing headlight bulbs
Before attempting a replacement, ensure you have the correct bulb type and a clean, safe workspace. The following steps apply to most 2010 Elantra headlight assemblies.
- Confirm the correct bulb sizes (H11 for low beams, 9005 for high beams) before purchasing.
- Handle bulbs by the base; avoid touching the glass with bare hands to prevent oil residue on the bulb.
- Disconnect the car battery or turn off the ignition before starting, and wear gloves to protect your hands.
- Install the new bulb securely and re-test the headlights before driving.
By following these steps, you reduce the risk of poor beam performance or premature bulb failure.
Summary
For a 2010 Hyundai Elantra, the standard configuration is low-beam H11 and high-beam 9005. Variations can occur by trim or region, so always verify with the manual or the vehicle’s labeling before purchasing or replacing bulbs.
