The Diode Dynamics 921 XPR LED bulb is a direct replacement for factory 921 incandescent bulbs, delivering a cool white appearance and 720 lumens per bulb for noticeably brighter signal and marker lighting. Each compact bulb places 16 high-power LEDs across four faces inside an aluminum housing with textured heatsinking and uses an inductive constant-current drive for reliable, plug-and-play installation.
