2018 Hyundai Elantra Headlight Bulb Size
Hyundai reshuffled the 2018 Elantra trim lineup by replacing the SE Limited with the new SEL and introducing a Value Edition that made this sedan one of the most budget-friendly commuters on the market. The 2018 Hyundai Elantra headlight bulb size is H11 for the low beams, 9005 for the high beams, and H11 for the fog lights. Base and Value Edition trims shipped with halogen reflector headlights that get the job done in city traffic but leave plenty of room for improvement on darker roads.
Upgrading to 2018 Hyundai Elantra LED headlights is the single best dollar-for-dollar improvement a cost-conscious owner can make. The swap takes minutes, requires no wiring changes, and every HID Nation kit comes with free shipping and a lifetime warranty that lasts as long as you keep the car.
Best LED Headlight Upgrade for the 2018 Elantra
The 2018 Elantra uses the same H11 low beam housing found across the sixth-generation platform, which means there is a wide range of proven LED options available. A quality LED conversion kit slots directly into the factory socket and produces a clean 6000K white beam with a well-defined cutoff line. Because LED bulbs generate far less heat than halogens, the Elantra's plastic headlight lenses stay clearer over time, avoiding the yellowing that heat-stressed housings often develop.
For owners who log serious highway miles, an HID xenon kit offers an alternative with slightly greater beam throw at distance. Installation requires mounting a slim ballast behind each headlight housing, adding about 15 minutes to the overall job. Once running, the HID output provides a dense, far-reaching beam that illuminates road signs and lane markings earlier than halogen or LED.
HID Nation backs every conversion kit with a lifetime warranty and ships every order free of charge. If anything fails, a replacement is on the way at no cost.
Frequently Asked Questions
What is the 2018 Hyundai Elantra headlight bulb size?
The 2018 Hyundai Elantra uses H11 bulbs for the low beams, 9005 (HB3) bulbs for the high beams, and H11 bulbs for the fog lights. The SE and Value Edition came with halogen headlights, while SEL, Limited, and Sport trims offered LED elements. The H11 low beam size is consistent across all 2018 Elantra trims.
How do I upgrade my 2018 Elantra to LED headlights?
Open the hood, reach behind the headlight assembly, and twist the H11 bulb socket counterclockwise to release it. Pull the old halogen bulb out, plug the LED replacement into the same connector, and lock the socket back into the housing. The entire process takes about 15 minutes per side with no tools required. HID Nation's LED kits are plug-and-play and include everything needed for a complete installation.
Is the 2018 Elantra Value Edition different from the SE for headlight upgrades?
No. The 2018 Elantra Value Edition and SE share identical headlight housings and bulb sizes: H11 low beams, 9005 high beams, and H11 fog lights. The Value Edition added features like a sunroof and blind-spot monitoring, but the headlight hardware remained the same. Any LED or HID kit that fits the SE also fits the Value Edition.
Are 2018 Hyundai Elantra LED headlights legal?
LED replacement bulbs that maintain the original beam pattern and cutoff are used widely in the 2018 Elantra without issue. The key is choosing a quality kit that positions the LED chips where the halogen filament sat, preserving the housing's intended light distribution. HID Nation kits are designed to replicate the factory beam geometry for a focused, road-friendly output.
What fog light bulb does the 2018 Hyundai Elantra use?
The 2018 Hyundai Elantra uses H11 bulbs in the front fog lights on equipped trims. Replacing the factory fog light halogen with an LED alternative gives you a cleaner white beam that pairs well with upgraded headlights and improves low-visibility driving in rain, snow, or dense fog.
