2017 BMW ALPINA B7 Bulb Size

When I first needed replacement bulbs for my 2017 BMW Alpina B7, I made a simple list so I wouldn’t guess at sizes. Think of it as a quick reference that lays out each lamp location, the common bulb type, and a practical note about fit or polarity. The small win is you can glance at the chart and know what to buy before you open the trunk or dashboard. As I built the list, I used a mental model: match lamp location to bulb code, then verify gauge and connector shape. A helpful rule of thumb is to cross-check the chart with your owner’s manual and a quick photo of the existing bulb. For validation, I link to parts I’ve used, and those links are affiliate links—if you buy through them I may earn a small commission at no extra cost to you. Quick recap: use the chart, confirm in person, replace confidently.
