## 2015-2019 Hyundai Sonata headlight bulbs: common questions

### What headlight bulb does a 2015-2019 Hyundai Sonata use?

H7 (halogen; projector or reflector depending on trim). Confirm in manual for the low beam and 9005 (HB3). Confirm in manual 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 2015-2019 Hyundai Sonata?

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.
