What Lighting System Does the 2020 Hyundai Tucson Have?
The 2020 Hyundai Tucson features an extensive lighting system with 13 bulb positions. It uses halogen technology with H7 LED low beams and 9005 LED high beams in a dual-bulb configuration. The Tucson has been available from 2005 to 2021, and the 2020 model falls in the late-generation years.
Can You Put LED Bulbs in a 2020 Hyundai Tucson?
To upgrade the 2020 Hyundai Tucson headlights to LED, you will need a H7 LED LED kit for the low beams and a 9005 LED LED kit for the high beams. Start with the low beams since they are used most often and have the biggest impact on nighttime visibility. For the fog lights, a H3 LED LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2020 Hyundai Tucson
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 2020 Tucson, 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 H3 LED fog light socket.

Standard halogen headlights on the 2020 Hyundai Tucson 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 6 years old, the original bulbs on your Tucson are likely overdue for replacement. Even if they still illuminate, reduced brightness significantly impacts nighttime safety. 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 2020 Hyundai Tucson?
The H7 low beam bulb on the 2020 Hyundai Tucson is a specific fitment. There are no widely recognized cross-compatible alternatives, so make sure to purchase the exact H7 size. For the high beams, the 9005 is interchangeable with HB3. 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.
