2015 BMW i8 Bulb Size

Misconception: many people think bulb charts are just a generic list that fits any car. Why it seems true: a lot of shopping sites show long lists and model names, so it looks safe to pick by category alone. Think of it as a labeling problem—names can match, but fit and function sometimes differ. What is true: this chart specifically maps bulb sizes and common replacements for a 2015 BMW i8, plus notes on LED or halogen options. A useful mental model is to match socket type, wattage, and beam pattern, not just the bulb code. Implications: you’ll avoid blown fuses, poor beam aim, or incorrect colors by checking those details. Quick recap and tests: confirm the bulb code on your owner’s manual or the lamp housing, test with the new bulb before final reassembly, and compare brightness and color temperature.
