What Lighting System Does the 2015 Hyundai Elantra Have?
The 2015 Hyundai Elantra features an extensive lighting system with 12 bulb positions. It uses halogen technology with 9005 LED low beams and H7 LED high beams in a dual-bulb configuration. The Elantra has been available from 1992 to 2020, and the 2015 model falls in the late-generation years.
Can You Put LED Bulbs in a 2015 Hyundai Elantra?
To upgrade the 2015 Hyundai Elantra headlights to LED, you will need a 9005 LED LED kit for the low beams and a H7 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 881 LED LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2015 Hyundai Elantra
The 9005 bulb uses a push-and-twist L-shaped bayonet lock. To remove the old bulb, disconnect the wiring harness first, then twist the bulb counter-clockwise and pull it out. Older model years like the 2015 Elantra typically offer easy access to the headlight bulbs from behind the headlight assembly under the hood. Most owners can complete the swap in under 10 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 881 LED fog light socket.

Standard halogen headlights on the 2015 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 11 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 2015 Hyundai Elantra?
The 9005 low beam bulb on the 2015 Hyundai Elantra is cross-compatible with HB3 bulbs. These share the same physical base and electrical connection, so they will fit the socket. However, 9005 is the recommended size because it is optimized for the wattage and beam pattern designed into your headlight housing. 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.
