CATEYE ViZ150 USB-C Rechargeable Bike Taillight — 150 lm Daytime Hyperflash, 300° Visibility

Designed for commuters, road cyclists and group riders who need a reliable rear light that stands out in daylight, the ViZ150 pairs OptiCube lens optics with an aggressive Daytime Hyperflash mode. It projects a long rear beam to extend the distance at which motorists notice you, and its multiple modes let you balance brightness and battery life depending on the ride.

How bright is the ViZ150 and what makes it visible during the day?

With 150 lumens in its Daytime Hyperflash setting and three high-efficiency LEDs behind the OptiCube lens, this light is engineered to cut through daytime glare. The lens design widens beam spread for side visibility while a focused rear projection helps drivers spot you from farther back.

• Peak output: 150 lumens (Hyperflash)
• OptiCube lens provides 300° side visibility
• Long rear beam projection increases detection distance

What runtime and modes can I expect for different rides?

The ViZ150 includes four distinct modes so you can trade intensity for endurance. Runtime varies widely depending on mode: a low constant setting for short commutes, long-duration flashing for all-day visibility, and a high-output Group Ride mode for increased presence among traffic.

• Constant (20 lm): ~5 hours — steady illumination
• Flashing (15 lm): ~70 hours — maximum runtime
• Group Ride (50 lm): ~11 hours — higher visibility for pelotons
• Daytime Hyperflash (150 lm): ~15 hours — peak daytime attention

How do I power and mount the light on my bike?

The ViZ150 uses a USB-C rechargeable battery for quick top-ups and simple charging routines; expect roughly three hours for a full charge. Its SP-15 seatpost bracket accommodates modern aero seatposts and the snap square base lets you mount the light vertically or horizontally to suit frame geometry.

• USB-C recharge in about 3 hours (cable not included)
• SP-15 bracket fits contemporary aero seatposts
• Snap square base for vertical or horizontal positioning
• Auto-save switches to flashing when battery is low

Will the ViZ150 suit my riding style and bike setup?

Compact yet powerful, the ViZ150 works for urban commuters, road cyclists who ride in groups, and anyone who cycles during daylight. Its small footprint and flexible mounting make it easy to install on aero seatposts or racks without interfering with saddle bags or accessories.

• Dimensions: 21 x 62.5 x 32.5 mm — compact profile
• Lightweight design preserves bike handling
• Multiple modes adapt to commuting, long rides, and group rides

Who this is for: The CATEYE ViZ150 is ideal for riders who prioritize daytime visibility and versatility. Choose it if you want a compact, rechargeable rear light that offers a high-output hyperflash for maximum attention, long-duration flashing for extended trips, and a secure bracket system that fits modern aero seatposts. It’s a practical upgrade for commuters, club riders, and anyone seeking to improve how quickly motorists detect them on the road.
