The 2020 BMW i8 uses LED bulbs for both the low-beam and high-beam headlights. The supplied fitment data does not list separate projector or non-projector headlight variations, so no headlight-type distinction is indicated for this model year.
Exterior lighting is LED throughout the listed applications. Front turn signals, daytime running lights, parking lights, and both front and rear side markers use LED bulbs. The rear lighting is also LED, including the tail lights, rear turn signals, brake lights, center stop light, and reverse lights. No fog-light bulb fitment is listed.
Interior and utility lighting uses LED as well, including the dome, map, instrument, interior, trunk, and step lights. The license plate lights are also LED. When replacing a unit, verify whether the vehicle uses an integrated LED lamp assembly rather than a replaceable bulb, since the fitment data identifies the light source as LED but does not provide conventional bulb-number codes.
