2019 BMW M550 Bulb Size

Decision: Provide a concise bulb size chart for the 2019 BMW M550i xDrive to help you identify the correct lamp types for headlights, fogs, and interior lights. Constraints include trim differences, market variations, and possible prior modifications, all of which create reasonable uncertainty that the chart aims to reduce rather than eliminate. Options: The list presents OEM part numbers and common aftermarket equivalents, with a comparison of brightness, color temperature, lifespan, and cost. Interpretation is based on evidence from fitment data and manufacturer specs, with limitations noted where fitment may vary or additional adapters are required. Recommendation and risks: Use the chart as a starting hypothesis, verify with your owner’s manual and physical inspection before purchase, and test fit before full installation.
