About the 2006 Subaru Impreza WRX STi Bulb Chart
This chart lists the recorded exterior and interior bulb positions for the 2006 Subaru Impreza WRX STi.
Sedan and Wagon versions can use different bulbs in the same light position.
Trim level and factory lighting equipment may also affect fitment, so two vehicles with the same year, make, and model are not always identical.
Compare the original bulb and socket before ordering a replacement.
Where a row is recorded as an LED unit, the lamp may be a complete assembly rather than a separately replaceable bulb.
Use the chart to identify the stored size, then confirm the part number on the lamp you remove.
Before ordering
Body style, trim, and factory lighting packages can affect fitment. Confirm the original bulb type and base before ordering a replacement. A replacement should match the recorded size and socket for that position on your vehicle.
