This 2004 Subaru Impreza bulb size guide helps you verify the correct replacement bulb by lighting position, so you can match the right lamp before you buy. Because Subaru used different bulbs depending on body style, trim, and lighting package, the chart is organized by location to make it easier to find the exact fit for your car.
Use this page as a quick reference for common exterior and interior lights on the 2004 Subaru Impreza, including headlights, turn signals, brake lights, parking lights, license plate lights, dome lights, and cargo area bulbs. It is especially useful when you want to compare sedan, wagon, WRX, WRX STI, and Outback-related fitments without guessing from the bulb shape alone.
For the best fitment results, always compare the bulb listed here with the one already installed in your vehicle, since trim and package differences can change the correct size. This is especially important if your Impreza has been converted to LEDs, uses aftermarket headlight assemblies, or has had fog lights, tail lamps, or interior lamps modified. Halogen and LED replacements may share the same base but still differ in beam pattern, brightness, and heat output, so check compatibility before ordering. If you are unsure, remove the old bulb and read the marking on the base before purchase.
