The Diode Dynamics interior LED bulb pack for 2015–2019 Subaru WRX STi replaces factory vanity, map, trunk, dome, and license plate incandescent bulbs with cool white LEDs for a cleaner, modern cabin look. Stage 2 delivers the highest increase in output for maximum brightness. The plug-and-play kit includes multiple 28mm, 31mm, and 194 bulbs, uses measured lumen ratings for accurate comparison, and employs constant-current circuitry to reduce flicker and extend life.
