Fog Light Bulb Size

The 2018 Hyundai Sonata uses 881 or H11 bulbs for its fog lights. Some models may also use 9006 (HB4) bulbs, depending on the specific trim level and configuration.

Importance of Fog Lights

Fog lights are crucial for improving visibility in adverse weather conditions. They are designed to illuminate the road directly in front of the vehicle, cutting through fog, mist, and heavy rain. Properly functioning fog lights can significantly enhance safety during challenging driving situations.

Replacing Fog Light Bulbs

Replacing the fog light bulbs in your 2018 Hyundai Sonata is a relatively simple process that can be done at home. Here's a step-by-step guide:

1. Locate the fog light assembly under the front bumper

2. Access the back of the fog light housing

3. Disconnect the electrical connector from the bulb

4. Remove the old bulb by turning it counterclockwise

5. Insert the new bulb, ensuring it's properly seated

6. Reconnect the electrical connector

7. Test the new bulb to ensure it's working correctly

Always handle halogen bulbs with care and avoid touching the glass part with bare hands, as oils from your skin can cause premature failure.

Choosing the Right Bulb

When selecting a replacement fog light bulb for your 2018 Hyundai Sonata, consider the following options:

  • Halogen bulbs: Standard option, affordable and widely available
  • LED bulbs: Brighter, longer-lasting, but may require additional modifications
  • HID bulbs: Extremely bright, but more expensive and complex to install

Ensure that the replacement bulb matches the original specifications to maintain proper light output and avoid potential legal issues.

Maintenance Tips

To keep your fog lights in optimal condition:

  • Clean the fog light lenses regularly
  • Check for cracks or damage to the housing
  • Ensure proper alignment for maximum effectiveness
  • Replace bulbs in pairs to maintain consistent illumination

By following these guidelines, you can ensure that your 2018 Hyundai Sonata's fog lights remain effective and reliable, enhancing your safety on the road.
