Cateye ViZ450 II TL-LD821 Taillight (Rechargeable Type C)

The Cateye ViZ450 II TL-LD821 is a rechargeable rear safety light designed for riders who want strong visibility in daylight as well as after dark. It suits road cyclists, commuters and endurance riders who spend time in traffic and want a rear light that remains conspicuous from more than just directly behind. The emphasis is on attention-grabbing visibility, practical charging and everyday usability rather than simply producing a continuous rear beam.

Made to be Noticed. The ViZ450 II combines rear-facing illumination with useful side visibility, helping approaching drivers recognise the rider from different angles at junctions and while overtaking. Dedicated daytime flashing behaviour increases conspicuity in bright conditions, while lower-output and group-riding options let the rider choose a less intrusive setting when full intensity is unnecessary. Mode memory also means the light can return to the previously selected setting instead of requiring repeated adjustment before every ride.

Practical for Daily Use. USB-C charging simplifies charging alongside modern electronics, while the replaceable battery gives the light a useful serviceability advantage over sealed units. Battery Auto Save automatically switches to a flashing mode when charge becomes low, helping preserve visibility rather than allowing the light to shut down unexpectedly. The supplied seatpost bracket is designed to accommodate conventional and contemporary aero-style posts, making the ViZ450 II suitable for a broad range of road, commuter and performance bicycles.
