What Lighting System Does the 2017 Hyundai Elantra Have?
The 2017 Hyundai Elantra features an extensive lighting system with 12 bulb positions. It uses halogen technology with HID-D5S LED low beams and HID-D1S LED high beams in a dual-bulb configuration. The Elantra has been available from 1992 to 2020, and the 2017 model falls in the late-generation years.
Can You Put LED Bulbs in a 2017 Hyundai Elantra?
To upgrade the 2017 Hyundai Elantra headlights to LED, you will need a HID-D5S LED LED kit for the low beams and a HID-D1S 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 LED Fog Light LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2017 Hyundai Elantra
To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. On the 2017 Elantra, 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 LED Fog Light fog light socket.

Standard halogen headlights on the 2017 Hyundai Elantra 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 9 years old, the original bulbs on your Elantra 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 2017 Hyundai Elantra?
The D5S low beam bulb on the 2017 Hyundai Elantra is a specific fitment. There are no widely recognized cross-compatible alternatives, so make sure to purchase the exact D5S 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.
