The Cateye VIZ450 II Rear Light [TL-LD821] featured here at Escapa is a high-power rear light designed to increase a cyclist’s visibility on roads, in the city, and on low-light trails. Its five red LEDs, OptiCube lens, and Daytime HyperFlash modes generate flashes of up to 450 lumens, providing a powerful light signal both day and night.

Its design offers rear and side visibility, helping cyclists be seen from different angles. It also features six lighting modes, a rechargeable and replaceable battery, a charge indicator, and a memory function that retains the last mode used.

Up to 450 lumens in daytime Mode

The Daytime HyperFlash modes are designed to improve visibility during the day, when ambient light can reduce the contrast of a conventional taillight. The most powerful mode reaches 450 lumens and offers an approximate runtime of up to 14 hours.

The focused lens concentrates the light to maximize its range, while OptiCube technology optimizes the light beam distribution and improves visibility from the rear and sides.

Six lighting modes

The Cateye ViZ450 II allows you to select the most appropriate setting based on traffic conditions:

- High: 35 Lumas and up to 5 hours of battery life.

- Low: 10 lumens and up to 18 hours.

- Flashing: 45 lumens and up to 65 hours of battery life.

- Group Ride: 45 Lumas and up to 15 hours.

- Daytime HyperFlash 1: 450 lumens and up to 14 hours.

- Daytime HyperFlash 2: 180 lumens and up to 20 hours.

The Group Ride mode provides lighting designed for riding in a group, avoiding a light that’s too distracting for cyclists riding behind you.

Rear and Side Visibility

The shape of the lens allows light to be projected toward the rear and sides, widening the angle from which the cyclist can be seen. This feature is especially useful at intersections, roundabouts, and merge lanes, where vehicles may approach from different directions.

USB-C Charging

The internal lithium-ion battery recharges via a USB-C connection and takes approximately three hours to fully charge using a 0.5 A power source. The USB-C cable is not included with the light.

Unlike many compact lights, the ViZ450 II’s battery is replaceable, a feature that helps extend the product’s lifespan as its charging capacity decreases.

Battery Auto Save System

When the battery level is low, the Battery Auto Save feature automatically switches the light to flashing Mode to reduce power consumption and extend runtime.

It also features a low-battery indicator and Mode memory, so the light reverts to the last settings used after being turned off and back on.

Compatible with Aerodynamic Seatposts

The included Cateye SP-15 mount fits both conventional seatposts and modern aerodynamic Kammtail-style profiles. It is compatible with diameters ranging from 21.5 to 32 mm and profiles with an outer circumference of up to 130 mm.

The Snap System makes it easy to attach and remove the unit, allowing you to quickly take it off to recharge it or avoid leaving it installed when the bike is parked.

IPX4 Water Resistance

The IPX4 rating provides protection against water splashes from various directions. This allows the light to be used in moderate rain and variable weather conditions, although it is not designed to be submerged.
