2003 Aston Martin Vanquish Bulb Size

Decision: This page exists to help you identify the correct bulb sizes for a 2003 Aston Martin Vanquish, reducing guesswork when replacing headlamps, indicators, or interior lamps. I present the evidence from parts catalogs and hands-on checks so you can compare OEM numbers with compatible alternatives. Constraints: space, fitment tolerances, and electrical compatibility limit choices; the list therefore includes each bulb’s size, socket type, and common performance variations such as color temperature and lumen output. Options range from exact OEM replacements to higher-output or longer-life aftermarket hypotheses, with interpretation notes about trade-offs. Comparison and recommendation: compare lifetime, heat generation, and plug-and-play ease before choosing; my recommendation favors matched-fit bulbs unless you accept wiring modifications.
