Daytime Running Visibility — Front and Rear in One Set

The Trek Ion 200 RT and Flare RT USB Rechargeable Set is a front and rear daytime running light combination designed to make you more visible while riding in daylight conditions. Daytime visibility is a distinct challenge from night riding — ambient light reduces the contrast that makes a cyclist stand out to drivers and other road users. This set addresses that directly with flash patterns and focused output specifically calibrated for daytime use, with a visibility range of up to 2km from the distinctive flash setting on both lights.

The Flare RT rear light is described as smaller and more powerful than previous versions, with an extended battery life and output designed for road, city, and path riding. The Ion 200 RT front light delivers 200 lumens via high-power CREE LED bulbs, packing the same core technology as the rear light into a compact front unit. Both lights are USB rechargeable, removing the need for disposable batteries and making regular charging straightforward with any standard USB source.

Both units include easy-to-mount brackets and can be attached to handlebars, a helmet, or a compatible bike mount, giving you flexibility in how and where you position each light depending on your setup.

Integrated Light Sensor and ANT+ Wireless Connectivity

Both the Ion 200 RT and Flare RT include an integrated light sensor that automatically adjusts brightness output based on the ambient light conditions around you. In brighter conditions the light increases output to maintain visibility; in lower light it adjusts accordingly. This automatic adjustment means the lights are always operating at an appropriate level without requiring manual intervention during the ride.

For riders with compatible ANT+ devices — including compatible cycling computers and head units — both lights can connect wirelessly via ANT+. This connection enables always-on functionality, battery status monitoring from your head unit, and wireless control of the lights without reaching down to adjust them manually. The ANT+ integration is compatible with supported devices only and requires a compatible ANT+ head unit or device to access these features.

Multiple Flash Patterns and Easy Installation

The set offers multiple flash patterns across both the front and rear units, allowing you to choose the pattern that suits your riding environment and personal visibility preference. The distinctive flash setting provides the 2km visibility range referenced in the product specification. For riders who prefer a steady beam or a different flash rhythm, the multiple pattern options give you control over how the lights present to those around you.

Installation is handled through the included easy-to-mount brackets, which attach the Ion 200 RT and Flare RT to your handlebars, helmet, or a compatible bike mount. The compact form factor of both lights means they add minimal bulk to your setup regardless of where you choose to position them.
