2012 Aston Martin DB9 Bulb Size

Goal: If you’re replacing bulbs on a 2012 Aston Martin DB9, this size chart solves the common problem of mismatched fittings and uncertain choices. I compiled the list from hands-on checks and parts data so you can pick the recommended bulb sizes quickly, with the trade-off of saving time over guessing. Prerequisites and step by step are straightforward: verify your trim and locate the existing bulb type, read the chart, then order the matching item. An assumption here is that modifications haven’t changed the stock sockets; validate by comparing part numbers before installation. Validation and troubleshooting: test each bulb after fitting and check for error messages or fit issues. Note: some links are affiliate and I may earn a small commission if you purchase.
