Illuminate your path
Front & Rear, Fully Covered
ATS-B03 lights the road ahead with 100 lux precision optics. TB04 keeps you visible from behind with Brake Warning that boosts to 90 lm the moment you slow down—complete visibility, both directions.
Auto Brightness Control
ATS-B03’s built-in ambient sensor automatically adjusts output as light conditions change—bright when you need it, reduced in daylight—without touching a button.
Brake Warning
TB04 automatically brightens to 90 lm output the moment it detects deceleration—steady and instant, so drivers behind you know you’re slowing down before they need to react.
Quick Release
Both lights remove in seconds—ATS-B03 with a tool-free quick-release lock, TB04 with a magnetic snap. Take them off, charge up, snap back on.
Fits Any Bike
ATS-B03 mounts on GoPro® or Garmin® compatible interfaces, facing up or down to suit your handlebar setup. TB04 fits Ø22.2–35 mm round and aero seat posts. Precision optics maintain a level rearward beam across seat tube angles from 70° to 90°, compatible with most bike models right out of the box.
