What Lighting System Does the 2021 Hyundai Kona Have?
The 2021 Hyundai Kona features an extensive lighting system with 13 bulb positions. It uses halogen technology with a single H7 LED dual-filament bulb handling both low and high beams. The Kona has been available from 2018 to 2023, and the 2021 model falls in the mid-generation years.
Can You Put LED Bulbs in a 2021 Hyundai Kona?
Upgrading the 2021 Hyundai Kona to LED headlights is straightforward since it uses a single H7 LED dual-filament bulb for both low and high beams. You only need one pair of LED bulbs to upgrade both functions. Look for a H7 LED LED kit that specifically supports dual-filament operation to ensure both beams work correctly. For the fog lights, a 12088 LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2021 Hyundai Kona
The H7 bulb uses a spring clip or wire retainer that holds the bulb in the socket. To remove the old bulb, disconnect the wiring harness first, then twist the bulb counter-clockwise and pull it out. On the 2021 Kona, you will likely encounter rubber dust covers behind the headlight housing. These pull off by hand or unscrew depending on the design. Allow about 15 to 20 minutes per side. When installing the new bulb, avoid touching the glass with bare fingers. Skin oils create hot spots that shorten bulb life. Wear clean gloves or handle the bulb by its plastic base only. The fog lights are accessed from underneath the front bumper. You may need to remove a few plastic clips or screws from the fender liner to reach the 12088 fog light socket.

Standard halogen headlights on the 2021 Hyundai Kona have an expected lifespan of 500 to 1,000 hours, which works out to roughly 2 to 3 years of normal use. Signs of a failing halogen bulb include noticeably dimmer output, a yellowish tint compared to the other headlight, or intermittent flickering. At 5 years old, your Kona is approaching the typical replacement window for halogen bulbs. Inspect your headlights at night and compare brightness between the left and right sides. When one headlight burns out, replace both sides at the same time. Bulbs from the same batch age at similar rates, and mismatched brightness is distracting to oncoming drivers.
What Bulbs Are Compatible with the 2021 Hyundai Kona?
The H7 low beam bulb on the 2021 Hyundai Kona is a specific fitment. There are no widely recognized cross-compatible alternatives, so make sure to purchase the exact H7 size. Using the wrong bulb size can cause improper beam patterns that reduce your visibility and blind other drivers. It can also cause overheating inside the headlight housing, potentially warping the plastic lens or reflector. Always verify the bulb number before purchasing.
