H7 (halogen on SE/SEL/Eco; LED projector standard on Limited/Sport from the 2019 facelift) for the low beam and H1 (halogen trims); LED module on Limited/Sport post-facelift for the high beam. Trims with factory LED or HID projectors use a sealed assembly instead and are not bulb-serviceable. ### Can you put LED bulbs in a 2017-2020 Hyundai Elantra? Physically, yes, LED replacements exist in every common base. Whether they work well depends on the housing: a reflector housing designed around a halogen filament scatters LED output into oncoming traffic instead of down the road. Projector housings tolerate the swap far better. Some vehicles also flag the lower current draw as a bulb-out fault. ## Sources - [Ontario Hyundai, Elantra oil type & capacity by model year (all AD engines)](https://www.ontariohyundai.com/service/service-and-parts-tips/hyundai-elantra-oil-type/) - [AMSOIL lookup, 2018 Elantra 2.0L MPI oil spec/capacity](https://www.amsoil.com/lookup/auto-and-light-truck/2018/hyundai/elantra/2-0l-4-cyl-engine-code-f-f/) - [AMSOIL lookup, 2018 Elantra 1.4L Turbo oil spec/capacity](https://www.amsoil.com/lookup/auto-and-light-truck/2018/hyundai/elantra/1-4l-4-cyl-engine-code-a-3-turbo/) - [AMSOIL lookup (CA), 2018 Elantra 1.6L Turbo oil spec/capacity](https://www.amsoil.ca/lookup/auto-and-light-truck/2018/hyundai/elantra/1-6l-4-cyl-engine-code-b-6-turbo/) - [NHTSA recall 21V-301, 2.0L Nu MPI piston oil ring defect](https://api.nhtsa.gov/recalls/recallsByVehicle?make=hyundai&model=elantra&modelYear=2019) - [NHTSA recall 17V-213, MDPS steering connector](https://api.nhtsa.gov/recalls/recallsByVehicle?make=hyundai&model=elantra&modelYear=2017) - [NHTSA recall 17V-063, brake booster failure](https://api.nhtsa.gov/recalls/recallsByVehicle?make=hyundai&model=elantra&modelYear=2017) - [Hyundai Motor America press release, 2022 Engine II litigation settlement](https://www.hyundainews.com/releases/3657) - [Edmunds, 2018 Elantra specs (curb weight, fuel tank, mpg)](https://www.edmunds.com/hyundai/elantra/2018/features-specs/) - [Cabin air filter 97133-F2000 fitment (2017-2023 Elantra)](https://personagrataagency.com/details/Cabin-Air-Filter-97133-F2000-Fits-Hyundai-Elantra-2017-2023/1173224) - [Engine air filter 28113-F2000 fitment (2017-2020 Elantra)](https://hyundai.oempartsonline.com/oem-parts/hyundai-air-filter-28113f2000) ## Other Hyundai Elantra generations - [2021-2025 Hyundai Elantra headlight bulbs](https://whichcarparts.com/cars/hyundai/elantra/2021-2025/bulbs) - [2012-2016 Hyundai Elantra headlight bulbs](https://whichcarparts.com/cars/hyundai/elantra/2012-2016/bulbs) Or [compare all generations](https://whichcarparts.com/cars/hyundai/elantra/bulbs). ## More for the 2017-2020 Hyundai Elantra - [Oil & filter](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/oil) - [Battery](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/battery) - [Tires & wheels](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/tires) - [Wiper blades](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/wipers) - [Air & cabin filters](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/filters) - [Brakes](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/brakes) - [Fluids](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/fluids) - [Service schedule](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/service-schedule) - [Problems & reliability](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/common-problems) - [Oil light reset](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/oil-reset) - [Key fob battery](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/key-fob-battery) - [Specs](https://whichcarparts.com/cars/hyundai/elantra/2017-2020/specs) Specifications vary with engine option, production date, and market.
