Most 2015 Hyundai Sonata models equipped with standard headlights use halogen bulbs. Specifically, the low beams are H11 and the high beams are 9005, with the fog lights typically using H11 as well. Some higher trims or aftermarket conversions may use HID or LED systems, which use different bulb types or modules.
Standard halogen headlights
Here are the common bulb types you’ll find in the standard configuration for the 2015 Sonata.
- Low beam: H11
- High beam: 9005 (HB3)
- Front fog lights: H11
When replacing bulbs, ensure you choose the correct wattage and handle new bulbs with care to avoid skin oils getting on the glass. If your car is not performing as described, double-check the owner’s manual or the bulb numbers on the current bulbs inside the headlight assembly.
Options and verification
Some 2015 Sonatas, particularly higher trims or those with optional packages, may use HID (xenon) headlights or LEDs instead of halogen bulbs. In those cases the replacement approach and bulb naming differ.
How to confirm your headlight type
To verify which system your specific vehicle uses, check the owner’s manual, inspect the bulb itself if you can safely access the headlight, or consult a Hyundai dealer or parts retailer with your Vehicle Identification Number (VIN) to confirm the exact bulb type for your trim and production date.
Summary
For most 2015 Hyundai Sonata models with halogen headlights, expect low beams H11, high beams 9005, and fog lights H11. If your vehicle has HID or LED headlights, the bulb types will differ (D2S/D3S for HID; LED modules for LED headlights). Always verify with your manual or a vehicle parts professional before replacing bulbs.
