2002 Aston Martin DB7 Vantage Bulb Size

Goal: help you identify correct bulb sizes for a 2002 Aston Martin DB7 Vantage, removing guesswork when replacing lamps. I write from hands-on experience and focus on practical constraints like socket type and clearance so you pick bulbs that fit and perform. Prerequisites and step by step: confirm the part number in the owner’s manual or by inspecting the old bulb, note whether the light is halogen, incandescent, or LED, and measure physical dimensions if space is tight. Then choose the recommended size and wattage, order replacements, and keep original bulbs until you validate fit and brightness. Validation and troubleshooting: fit each bulb, test in low and high beams, and check for error codes or flicker—LEDs may require resistors due to polarity or CAN errors.
