KNOG Plus Rear Bike Light, Black, Rear Style USB-Rechargeable LED Tail Light with Clip, Waterproof 17g

KNOG Plus is a compact, USB-rechargeable rear bike light that delivers high-visibility LED output, waterproof reliability, and multiple mounting options for commuting or night rides.

Whether you ride for errands, training, or leisure, the KNOG Plus Rear Bike Light is built to make you easily seen after dusk or in poor weather. Combining a slender 17 g body, integrated USB-A charging and a weatherproof seal, this taillight balances brightness and battery life so you can stay visible without bulky accessories. The light's removable clip unlocks wearable uses beyond the bike, while multiple flash and steady modes give you flexible visibility choices.

How bright is the KNOG Plus and how far can drivers see it?

The Plus uses efficient LED (COB-style) illumination tuned for rear visibility rather than a blinding beam. In standard settings it produces up to 20 lumens and a visibility envelope that stretches out to roughly 450 meters in clear conditions, helping motorists and other cyclists pick up your position earlier.

• Rated visibility around 450 m (about 1,400 ft) in clear sightlines.
• Multiple modes: steady and several flashing patterns for different traffic situations.
• Low-power settings extend runtime when brightness isn't needed.

What mounting options does the taillight offer for bikes and beyond?

The Plus arrives with a simple seat-post/stay mount that secures the unit to round or aero tubing, and the light itself detaches to serve as a clip-on wearable. That versatility means you can switch from a bike tail light to a jacket, backpack, or helmet light in seconds.

• Silicone mount fits a wide range of seat post and stay diameters.
• Quick-release clip converts it into a wearable running or camping light.
• Low height profile avoids interference with panniers or racks.

How long does the battery last and how do you recharge it?

Built for practical everyday use, the Plus delivers long runtimes on lower-power modes and still supports useful durations on brighter settings. Recharge is straightforward thanks to the built-in USB-A plug—no cable to carry—and an LED ring shows charging progress and low-battery alerts.

• Up to about 40 hours in low-power mode; shorter runtimes for brighter flashes.
• Integrated USB-A connector for direct, cable-free charging from any USB port.
• Charging / battery indicator ring around the control button for quick checks.

Is the Plus durable enough for wet weather and daily use?

Yes—the housing is sealed to an IP66 rating, so it's protected against heavy sprays and most wet conditions encountered commuting or training. The lightweight construction (17 g) also resists snagging or bouncing, while the simple controls and solid mount keep it reliable under regular use.

• IP66 water resistance shields electronics from driving rain and road spray.
• Robust clip and mount materials resist wear from frequent attachment/removal.
• Minimal moving parts reduce the chance of mechanical failure.

Who is this for? The KNOG Plus Rear Bike Light is aimed at commuters, evening riders and multi-sport users who want a no-fuss, lightweight taillight that’s easy to charge and move between bike, bag or clothing. If you value compact gear, reliable weather protection and visibility-first lighting for urban or recreational riding, the Plus fits neatly into your kit.
