Factory bulb sizes and relevant BulbFacts-tested replacement evidence for the 2020 Hyundai Elantra.

These products were physically tested by BulbFacts, but the tests were not performed in this exact vehicle unless a card explicitly says otherwise.
High/Low Beam Combined: 9005 / HB3

Fitment note: Verify the installed bulb, connector, housing, and factory system before ordering. A bulb-size match is not automatically a conversion recommendation or proof of vehicle-specific testing.
