2020 BMW 740 Bulb Size

Misconception: people often think one bulb size list fits every 2020 BMW 740i variation. It seems true because many parts look interchangeable, and retailers lump models together. Think of it as a shortcut that can lead to the wrong fit. What is true: trim level, headlight option, and socket type change the exact bulb sizes for a 2020 BMW 740i. A simple mental model is to match both the part number and the lamp function, not just the model year. The implication is you save time and avoid returns by checking your car’s socket and existing bulb. Quick recap and tests: verify the bulb code stamped on the bulb, compare photos, and test-fit before finalizing.
