2020 BMW M5 Bulb Size

Goal: help you quickly identify correct bulb sizes for a 2020 BMW M5 when a lamp fails or you’re planning upgrades. The problem is small differences in trim and options can change bulb types, so the list focuses on the most common factory configurations and notes where variations may apply. Prerequisites and step by step: use your VIN or inspect the existing bulb socket to confirm fitment, then consult the chart for socket and wattage. The recommended approach is to treat the chart as a guide, not a substitution for visual validation. Assumption is factory equipment unless you have aftermarket lighting. Validation and troubleshooting: verify part numbers and test the new bulbs before reinstalling trim.
