2021 MINI Convertible Bulb Size

Goal: This bulb size chart is meant to remove guesswork when replacing lights on a 2021 MINI Cooper. The problem is mismatched bulbs and wasted time. Use the list to confirm socket type, wattage, and fit before ordering so you avoid returns and electrical issues. Prerequisites and steps are simple. Inspect the existing bulb and housing, compare markings to the chart, and follow the recommended replacement sizes. Validate fit by testing the bulb in the vehicle before final installation. A common trade-off is choosing brighter aftermarket options that may reduce lifespan or require adapters; make that choice with the vehicle’s constraints in mind.
