2020 Porsche Cayenne Bulb Size

Decision: This bulb size chart exists to identify the correct replacement lamps for a 2020 Porsche Cayenne and reduce guesswork when sourcing parts. The list provides socket types, bulb codes, and typical fitment notes so you can match evidence from your vehicle to options available. Constraints: Model-year variations and trim packages introduce limitations, so the chart frames a hypothesis about common fits rather than a single definitive answer. Options cover OEM-equivalent and aftermarket bulbs; comparison focuses on compatibility, brightness, and longevity so you can interpret trade-offs with clear criteria. Recommendation and risks: Use the chart as a reference, verify fit by inspecting your vehicle, and consider OEM for critical safety lamps.
