Shadow Flow
Underglow Chassis Kit
The Shadow Flow turns every parking lot into a car show. Flexible RGB LED strips mount under your chassis to create a vivid, head-turning underglow that reflects off the pavement beneath your car. Encased in waterproof silicone, these strips survive anything the road throws at them — puddles, salt, gravel, speed bumps. The flowing color animation creates a dynamic, moving light effect that looks like your car is hovering on a bed of neon. Dual control via remote and app gives you instant access to solid colors, flowing patterns, breathing effects, and strobe modes. CE certified and built for daily driving.
