2007 Aston Martin DB9 Bulb Size

Goal: help you quickly identify correct bulb sizes for a 2007 Aston Martin DB9 so you avoid buying the wrong parts. Start by locating the specific lamp (head, fog, tail) and noting the socket type; the list assumes common factory fittings and highlights any constraints or exceptions. Step by step: use the chart to match socket codes to bulb types, then cross-check part numbers against your owner’s manual for validation. I recommend noting the trade-off between OEM fit and aftermarket options, and confirming polarity or wattage before purchase to prevent electrical issues. Troubleshooting and wrap up: if a bulb doesn’t fit, recheck the socket and test another listed option or consult a mechanic.
