2017 BMW i8 Bulb Size

Misconception: people think a single bulb size list will fit every light on a 2017 BMW i8, so swapping bulbs is quick and simple. Why it seems true: many cars use similar sockets, and sites list sizes in one place, so it feels like a reliable rule of thumb. What is true: the i8 uses different bulb types for low beam, high beam, fog, and interior lights. Think of it as a mental model where each circuit can have its own spec, not one universal part. This chart aims to save you time by listing each socket size and common replacements. Implications and quick recap: use the list to verify before buying and test fitment quickly. Quick tests: check your owner's manual, compare part numbers, and verify physical socket before installation. Affiliate note: links may earn a small commission at no extra cost to you.
