This 2006 Subaru Impreza bulb size guide helps you quickly verify the correct bulbs by lighting position, so you can match the right part before you buy. Because Subaru used different lighting setups across trims, body styles, and markets, the exact bulb can change depending on where it is installed.
Use this page to check common exterior and interior bulb locations on the 2006 Subaru Impreza, including headlights, turn signals, tail lights, dome lights, and more. If you are replacing one bulb or planning a full refresh, confirming the bulb by position is the safest way to avoid fitment mistakes.
Fitment can vary between sedan and wagon models, as well as between base trims, WRX, WRX Limited, and WRX STI versions. Some positions use halogen bulbs, while others may be listed with LED or have different bulb options depending on the original equipment. If your Impreza has been modified with aftermarket lighting, projector retrofits, or LED conversions, always compare the installed bulb to the chart before ordering. The best practice is to remove the old bulb and check the base type and markings first, especially for headlights, fog lights, and rear signal lamps where trim-specific differences are common.
