The following sections detail five products, including design notes, practical uses, and how their features translate to everyday cycling safety.
CATEYE ViZ USB Daytime Safety Light (1 Mile)

The ViZ Daytime Safety Light combines bright daytime output with OptiCube lens technology to maximize daytime visibility. Using 150 lumens in Daytime Hyperflash mode, it signals presence to drivers from a distance, potentially increasing reaction time. The light supports four modes, including a longer runtime option for night riding. Its IPX4 rating provides splash resistance for riding in light rain, making it suitable for mixed-weather commutes and road adventures.
CATEYE ViZ USB Daytime Safety Light (1.2 km Reach)

This variant ramps up brightness to 300 lumens with Daytime Hyperflash, extending visibility up to about 0.7 miles. The longer reach improves conspicuity when approaching intersections or in heavy traffic. It shares the same OptiCube lens design and four-mode operation, balancing daytime signaling with a reliable nighttime option for consistent safety across riding conditions.
CATEYE Omni 5 Bike Safety Light

The Omni 5 focuses on all-around visibility with 360-degree coverage. Its 5 LED array delivers high brightness with multiple flashing modes to suit urban streets, country roads, and dim trail segments. The AAA battery design and up to 120 hours of runtime help ensure dependable visibility for long commutes or weekend rides, while IPX4 waterproofing supports use in light rain and splashes.
Smart Bike Tail Light With Brake Sensing

This model integrates smart brake sensing to boost rear brightness during deceleration, helping traffic behind you react sooner. It features auto-on/off via vibration, a 30-second auto-sleep function, and five dynamic modes powered by 22 high-lumen COB LEDs arranged in a ring. A 500 mAh USB-C battery offers up to 15 hours of runtime, supporting extended night rides and multi-day trips with reliable visibility.
CATEYE Omni 3 Bike Safety Light

The Omni 3 delivers 360-degree visibility with three wide-angle LEDs and multiple modes to suit beginner riders through to seasoned cyclists. Aquiring up to 150 hours of runtime, this light prioritizes endurance for longer rides or daily commuting. Its compact form and IPX4 rating make it a practical option for riders who want reliable, all-around visibility without bulk.
Buying Guide
When choosing a cat eye rear light, consider these key purchase factors to balance visibility, battery life, and portability:
- Brightness and beam pattern: Daytime Hyperflash modes maximize daytime conspicuity, while nighttime modes provide steady illumination. A 300+ lumen option offers greater distance visibility, especially on faster roads.
- Modes and control: Look for multiple modes (constant, flashing, rapid, group ride) and easy-to-use controls. Anti-drain features and memory recall can help simplify use across rides.
- Battery type and runtime: USB-C rechargeable batteries are common and convenient. Longer runtimes (50+ hours in flashing modes) are beneficial for multi-day trips and irregular charging opportunities.
- Water and dirt resistance: IPX4 is standard for rain splash protection; IP65 offers better protection against water and dust for rough weather or dusty trails.
- Mounting compatibility: Ensure the light fits your bike type (road, MTB, gravel) and works with your current seat stay or seatpost mounting system.
- Size and weight: A compact rear light minimizes bulk but should still deliver sufficient brightness. Consider how it affects aerodynamics and handling on aggressive rides.
- Reliability features: Brake-sensing lights, auto on/off, and secure mounting reduce the risk of light failure mid-ride and improve safety in traffic.
Choosing between 150 to 300 lumens for daytime riding and higher lumen options for high-traffic environments depends on your usual routes and local lighting. For urban commutes, daytime high-visibility modes are particularly helpful. For mountain or gravel trails, a light with robust waterproofing, a wide beam, and longer runtime becomes more critical. Battery life, ease of recharge, and mounting flexibility should align with how you ride and where you ride most often.
