2013 Aston Martin DB9 Bulb Size

Many owners replacing bulbs for a 2013 Aston Martin DB9 run into compatibility issues and wasted time matching sizes. As a technician who works on high-end cars, I created this bulb size chart to remove guesswork. It lists the OEM socket types, common aftermarket equivalents, and recommended wattage so you can plan purchases with realistic trade-offs between brightness and heat. Use the chart as a parts checklist and validation tool when ordering. Check the socket type against your car before installation and note any constraints like CAN-bus warnings or adaptive lighting modules. My assumption is you have basic tools and can access the lamp housings. If you need to swap choices, follow fit and polarity checks described in the chart.
