What Lighting System Does the 2006 Subaru WRX STI Have?
When it comes to nighttime visibility, the 2006 Subaru WRX STI relies on an arrangement of 13 specialized bulbs. It features an extensive lighting system powered by premium factory HID/Xenon technology utilizing D2S projector housings for high-intensity output.
Can You Put LED Bulbs in a 2006 Subaru WRX STI?
The 2006 Subaru WRX STI is already equipped with factory D2S HID/Xenon headlights. Since HID technology already provides exceptional brightness, we recommend staying with high-quality OEM replacement bulbs rather than attempting an LED retrofit for the primary headlights. However, the H3 LED fog lights are typically halogen and are excellent candidates for an LED upgrade to match the color temperature of your HID headlights.
