The Diode Dynamics interior LED bulb pack for 2015–2019 Subaru WRX STi refreshes the cabin with blue LEDs in a plug-and-play replacement for vanity, map, trunk, dome, and license plate incandescent bulbs. Stage 1 provides a subtle brightness lift and color update. The included 28mm, 31mm, and 194 bulbs come with measured lumen ratings and are built with constant-current circuitry and transient suppression for consistent, long-term performance.
