BMW 640 Bulb Size By Years
Misconception: swapping bulbs is just about size, so any bulb labeled “H8” or “LED” will fit. It seems true because labels feel like a universal shorthand, and many parts sellers list size without context. Think of it as a tempting shortcut that can lead to wrong fit or poor beam pattern.
What is true is that fit, connector type, and light output all matter, especially on a 2017 BMW 640i. This list’s purpose is to match the correct bulb numbers to each socket and note common replacements and upgrades. The mental model here is fit + function, a simple rule of thumb that keeps optics aligned and avoids dash errors.
Implications are practical: follow the chart, verify your socket, and test before finalizing. Quick tests include checking connector shape and doing a bench swap. Quick recap: use the chart as a starting guide. Affiliate disclaimer: some links may earn a small commission at no extra cost to you.
