This 2005 Subaru Legacy bulb size guide helps you verify the correct replacement bulb by lighting position, so you can match the part to the exact lamp on the car. Because Subaru used different bulbs depending on body style, trim, and lighting package, it is important to check the location first before ordering.
Use this page as a quick reference for common exterior and interior bulbs on the 2005 Legacy, including headlights, tail lights, turn signals, map lights, dome lights, license plate lights, and cargo area bulbs. The listed sizes are organized to make replacement easier whether you drive a sedan or wagon.
For the best fitment results, compare your vehicle’s trim and package with the bulb chart before buying. Some positions may use different bulbs on sedan versus wagon models, and some lighting setups can vary by market. If you are switching from halogen to LED, make sure the replacement is compatible with the socket, polarity, and any required load resistors or CAN-bus style accessories. Aftermarket conversions can change beam pattern or brightness, especially in headlight and fog light housings, so it is smart to test the lights after installation. When possible, remove the installed bulb and confirm the marking on the base before purchasing a new one.
