This 2019 BMW i3 bulb size guide helps you verify the correct bulb or LED type by lighting position, so you can match the right part before you buy. Because the i3 can use different lighting setups depending on trim, market, and package, checking the exact location on the vehicle is the safest way to confirm fitment.
On this page, you can look up exterior and interior lighting points such as the headlights, brake lights, license plate lights, reverse lights, side markers, cargo area light, and cabin lights. For the 2019 BMW i3, many positions are listed as LED, while some interior or comparison entries may use traditional bulb numbers like 2825, 98, H11, or 64132 depending on the original configuration.
Fitment can vary by trim, lighting package, body style, and region, so always compare the bulb position on your car with the chart before ordering. The 2019 BMW i3 may have LED lighting in many locations, but some entries are shown as compare-to-original options or alternate setups, which is important if you are replacing a factory bulb or converting to aftermarket LEDs. If you are switching from halogen to LED, make sure the replacement is compatible with the socket, polarity, and any vehicle warning system. When possible, remove the installed bulb and check the markings on it before purchase, especially for interior lights and front turn signal options where more than one fitment may appear in the catalog.
