2018 Bentley Mulsanne Bulb Size

Misconception: many people think any bulb that fits is fine for a 2018 Bentley Mulsanne. It seems true because sockets look the same and online listings match part numbers, so swapping feels simple. Think of it as a mental model issue: fit is one thing, beam pattern and wattage affect performance and optics. What is true is that bulbs must match the Mulsanne’s optical design and electrical tolerances for safe, legal light output. The implication is that choosing the right size from this chart helps avoid glare, overheating, or reduced lifespan. Quick tests: compare part numbers, check beam pattern, and monitor heat after a short drive. Quick recap: this list aims to save time and prevent guesswork.
