2018 Audi R8 Bulb Size

Decision: This bulb size chart exists to help you match replacement bulbs to the specific sockets and lamp functions of a 2018 Audi R8, reducing trial-and-error and fitment issues. Evidence from fitment guides and owner reports informs the list, while a cautious interpretation of variations between model trims guides the recommendations. Constraints and options: The chart notes limitations such as trim differences, aftermarket vs OEM sizing, and region-specific regulations, and then lists compatible bulb types so you can compare options side by side and form a hypothesis about the best balance of brightness, longevity, and compatibility. Recommendation and risks: I recommend using the chart as a starting point and confirming physical fit before purchase; affiliate links in the chart may generate a small commission at no extra cost to you, which supports maintenance of this resource and does not influence the objective comparison.
