Trek Ion 200 RT/Flare RT USB Rechargeable Set Light

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.
