This 2009 Subaru Legacy bulb size guide helps you verify the correct bulbs by lighting position, so you can replace the right lamp without guesswork. Whether you are changing a headlight, tail light, license plate light, or reverse bulb, matching the bulb to the exact location is the easiest way to avoid fitment mistakes.
The 2009 Legacy can use different lighting setups depending on trim, market, and body style, so it is smart to confirm the bulb chart before buying replacements. Use this page as a quick reference for common exterior bulb positions on the 2009 Subaru Legacy, including front, rear, and license plate lighting.
For the best fit, compare the bulb type on your vehicle with the chart and check the installed bulb before ordering, especially if your Legacy has an optional lighting package or has been modified. Halogen bulbs and LED replacements are not always direct swaps, and some aftermarket LED conversions may need resistors, adapters, or a different beam pattern to work properly. If a previous owner changed any bulbs, the installed part may differ from the original specification, so a quick visual check can save time and prevent returns.
