If you’re replacing bulbs on a 2021 BMW Alpina B7, the list solves the common problem of mismatched sizes and wasted time. The chart’s goal is to show recommended bulb types and locations under the assumption vehicle specifications match factory trim. It also notes constraints where optional packages change fitment. Use the chart as a first step, then validate against your owner’s manual and the existing bulb part numbers. The step-by-step approach is simple: identify location, compare size, and confirm fitment.
