This page is a quick reference for the 2020 Hyundai Ioniq EV and the bulb sizes commonly listed by lighting position. It is designed to help you verify the correct bulb before you buy, whether you are replacing a headlight, marker light, interior lamp, or a rear signal bulb.
Because bulb fitment can vary by trim, market, and body style, use the position-specific chart on this page rather than guessing by appearance alone. Matching the bulb to the exact location is the safest way to get the right replacement the first time.
For the 2020 Hyundai Ioniq EV, fitment can change with trim level, lighting package, and whether the car uses halogen or LED equipment in a given position. Some vehicles may also have aftermarket conversions or previous repairs that changed the original bulb type. Before ordering, it is a good idea to remove the installed bulb and compare the base, connector, and markings to the chart. That extra check is especially useful for headlight and exterior signal bulbs, where the same model year may use different setups in different markets.
