The Trek Ion Pro RT and Flare RT set pairs a front light with a rear light for trail and road rides where visibility matters day and night. The Ion Pro RT throws a powerful beam across the full width of the road or trail, while the Flare RT adds a daytime running rear light with flash patterns visible from up to two kilometres away.
Both lights are rechargeable and mount easily to handlebars, a helmet, or a compatible bike mount, with adjustable mounts and charging cables included in the set. ANT+ connectivity lets compatible devices show always-on status and battery level and allows wireless control, giving riders a coordinated front and rear lighting setup managed from one connected system.
