CATEYE ViZ150 USB‑C Rechargeable Rear Safety Light — 150‑lumen Daytime Hyperflash, OptiCube 300° Visibility

The CATEYE ViZ150 is a compact USB‑C rechargeable rear safety light that delivers up to 150 lumens of daytime Hyperflash visibility for cyclists.

Designed to maximize rear visibility in daylight and low‑light urban conditions, the ViZ150 combines OptiCube lens optics, long‑reach beam projection and a compact housing to help other road users detect you earlier. It mounts on modern aero seatposts with the included SP‑15 bracket or snaps into multiple orientations for flexible positioning. The light balances a very bright daytime flash with long runtime modes for commuting, group rides and all‑day outings.

How bright is the ViZ150 and when should I use the 150‑lumen mode?

The ViZ150 produces a powerful 150‑lumen Daytime Hyperflash designed to attract attention during sunny or busy daytime conditions. Use the Hyperflash when you need maximum visibility to drivers and cyclists at greater distances; switch to lower modes when conserving battery or riding in dim light.

• 150 lumen Daytime Hyperflash for daytime visibility
• OptiCube lens for wide 300° visibility
• Long rear beam projection extends effective detection range
• Switch to lower modes for extended rides or night use

What run times and modes does this safety light offer?

The ViZ150 offers four distinct modes to balance brightness and battery life: Constant, Flashing, Group Ride and Daytime Hyperflash. Each mode suits different conditions—steady for low light, flashing for long commutes, group ride to maintain visibility among cyclists, and Hyperflash for high‑visibility daytime use.

• Constant (20 lumens): approximately 5 hours
• Flashing (15 lumens): up to 70 hours for long commutes
• Group Ride (50 lumens): about 11 hours for riding with others
• Daytime Hyperflash (150 lumens): roughly 15 hours of high‑impact bursts

How do I recharge and mount the light for reliable use?

Recharge the ViZ150 quickly via USB‑C in around three hours; the charge port supports common USB‑C cables (cable sold separately). The included SP‑15 bracket fits modern aero seatposts, while the snap square base lets you mount the light vertically or horizontally for the best beam orientation.

• USB‑C rechargeable — ~3 hour charge time
• Battery auto save switches to flashing when power is low
• SP‑15 bracket fits contemporary aero seatposts
• Snap square base allows vertical or horizontal positioning

How visible will I be from different angles and distances?

OptiCube lens technology produces a broad 300‑degree light spread so motorists and other cyclists can see you from the rear and sides. Combined with long rear beam projection, the ViZ150 increases the effective distance at which you are noticed, giving others more time to react.

• 300° visibility from the OptiCube lens
• Focused rear beam projection extends sightline distance
• Hyperflash pattern optimized for daytime attention
• Compact profile reduces wind drag and stays secure on the seatpost

Who is this for: The CATEYE ViZ150 is aimed at commuters, urban riders and group cyclists who need a compact, high‑output rear light that performs in bright daytime traffic and long rides. It suits riders with modern aero seatposts who want quick USB‑C charging, multiple runtimes for varied use, and a versatile mounting design for optimal beam placement.
