Most 2019 Optima models with halogen headlights use H11 for the low beams and 9005 for the high beams. If your Optima has HID or LED headlights, the bulb type will differ and is not interchangeable with standard halogen bulbs.
Common bulb configurations for the 2019 Optima
These are the typical bulb codes you may encounter, depending on the headlight setup your car came with.
- Low-beam headlight: H11
- High-beam headlight: 9005 (HB3)
- Fog lights (if equipped): commonly H11, though some trims may differ
Knowing the exact bulb type depends on the trim and headlight configuration. If in doubt, verify with the manual or a parts specialist.
How to verify the exact bulb for your car
To be sure you source the correct bulb, follow these verification steps.
- Identify whether your Optima uses halogen, HID, or LED headlights by checking the owner’s manual, the window sticker, or the headlight assembly.
- If you can access the current bulb, remove it and read the stamping on the base (for example, H11 or 9005) to confirm the exact code.
- Consult the owner's manual or Kia’s official parts catalog for your exact year, trim, and market (you can also use your VIN) to confirm the recommended bulb type.
- If you’re unsure, contact a Kia dealer or a reputable auto parts retailer with your vehicle details to verify the correct bulb.
Clear identification helps ensure you replace the bulb with the right type and avoid compatibility issues.
