What headlight bulb does a 2021–2025 Hyundai Elantra use?

LED standard on Limited/N Line/N/Hybrid Limited; halogen projector on SE/SEL for the low beam and LED (upper trims); halogen (SE/SEL) 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 2021–2025 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.
