2014 Aston Martin DB9 Bulb Size

Goal: This list helps you match replacement bulbs to the correct sockets on a 2014 Aston Martin DB9, reducing guesswork and fitment errors. Prerequisite: have the vehicle manual or the original bulb to confirm part numbers when possible, and accept the trade-off that aftermarket options may differ slightly in output. Step by step: use the table to identify bulb type per function, compare the socket and wattage, then buy the recommended size. Validation: cross-check the listing against the part stamped on the bulb or the owner’s manual before installation. This reduces unnecessary returns and respects practical constraints. Troubleshooting and wrap up: if fit or brightness seems off, verify polarity and connector fit first.
