Info
The Lezyne Strip Pro Alert 400 Rear Light is a powerful, intelligent taillight designed to keep cyclists highly visible and safe on the road. With a maximum output of 400 lumens from its 10 LEDs, this light ranks among the brightest and most powerful rear bicycle lights available. It features custom-programmed alert technology that acts like a smart brake light: when you slow down or stop, the light automatically switches to a sharp 150-lumen flash to alert drivers and fellow riders
This advanced "Ai Alert" system uses built-in sensors to detect deceleration, effectively communicating your movements to traffic and enhancing safety during group rides or city commutes.
Built for real-world cycling, the Strip Pro Alert 400 offers seven different modes to suit any condition – from the highly disruptive Daytime Flash mode (max 400 lm bursts) to an ultra-long Femto mode for up to 80 hours of runtime.
Use the eye-catching Daytime Flash to stay visible under bright sunlight, or switch to a steady Economy beam for night rides. The light’s wide-angle optics provide a broad 270° field of visibility, ensuring you’re seen not just from behind but from the sides as well. No matter if it’s daylight or dusk, fast traffic or a quiet trail, you have a mode that maximizes your visibility.
Durability and convenience are top-notch. The Strip Pro Alert 400 is crafted with a co-molded, IPX7 waterproof construction, which means it can withstand heavy rain and splashes without issue. Its versatile mount attaches securely to both aero and round seatposts, using a robust silicone strap that keeps the light stable even on bumpy roads. The unit is lightweight (approximately 71 g) yet rugged, built to handle daily use and rough terrain. When it’s time to recharge, a high-capacity 1900 mAh battery powers the light for days and recharges via a modern USB-C port (waterproof cover included). This gives you quicker charging, easy cable compatibility, and no need for disposable batteries – simply plug it in, power up, and you’re ready to ride.
Key Benefits
- Ultra Bright 400 Lumen Output: Ten high-output LEDs deliver up to 400 lumens of red light, making it one of the strongest rear bike lights in its class. This ultra-bright output ensures exceptional visibility day or night, helping drivers spot you from a distance even under sunlight.
- Smart Brake Alert Technology: “Ai Alert” brake-sensing tech instantly triggers a distinct 150-lumen flash when you decelerate. Just like a car’s brake light, it clearly signals others that you’re slowing or stopping, greatly enhancing safety at intersections and in group rides.
- Multiple Modes for Day & Night: Choose from 7 versatile modes (2 steady beams and 5 flash patterns) to match your riding conditions. The highly disruptive Daytime Flash mode blasts at 400 lm to grab attention in daylight, while the Femto mode extends runtime up to 80 hours for long night rides. You can adapt on the fly for city commutes, daytime training, or after-dark trails.
- Wide 270° Visibility: Special wide-angle optics give you 270° of visibility, far more coverage than a standard rear light. This means traffic approaching from the side – not just directly behind – can see your light. Increased side visibility is crucial at junctions and driveways, adding an extra layer of safety.
- Long Battery Life & USB-C Rechargeable: Powered by a robust 1900 mAh battery for extended run times, this light can last multiple days of commuting on a single charge. When needed, recharge quickly via the USB-C port (fast-charge compatible). It’s a convenient, eco-friendly solution that eliminates the cost and waste of disposable batteries, and the USB-C interface is water-resistant for reliability in wet conditions.
- Rugged & Weatherproof Build: Built to IPX7 waterproof standards, the Strip Pro Alert 400 shrugs off rain, puddles, and mud. Its durable co-molded housing protects the electronics from shock and vibration, so it won’t crack or fail from regular use on rough roads. You can ride with confidence that your light is engineered to endure tough weather and terrain.
- Easy Seatpost Mounting: The light mounts securely in seconds with an included silicone strap. The design is compatible with both round and aero seatposts, ensuring a snug fit on any road, mountain, or hybrid bike. This versatile mount means you can easily transfer the light between bikes or adjust its angle for optimal visibility. No tools required – just strap it on and go.
Key Features
- Intelligent Brake Alert: One of the few rear lights on the market that automatically signals braking. The built-in sensor triggers a bright flash when you slow or stop, which is a standout safety feature competitors often lack or don’t execute as effectively.
- Blinding Daytime Visibility: With a 400 lumen output (far higher than many standard tail lights), this model is designed for visibility even in broad daylight. It’s an ideal choice for riders who demand a strong rear light for busy roads or daytime training rides.
- Endurance and Reliability: Offers extremely long run times (up to 80 hours on a charge) thanks to an efficient power management design. Fewer recharge cycles are needed compared to other lights, and the USB-C charging adds convenience and future-proof compatibility. Plus, an aluminum heat-dissipating body (with cooling fins) prevents overheating on high-output modes, a detail not all rivals consider.
- All-Weather Durable: Fully water-resistant to IPX7 standard – a level of durability that outclasses many competitors. Rain or shine, this light keeps working, whereas cheaper alternatives might fail in heavy rain. Its robust construction means it can survive drops and rough use, making it a long-term investment.
- Wide-Angle & Adaptable Mounting: The 270-degree beam angle covers more area than typical rear lights, which usually have a narrower focus. This wide visibility can be a lifesaver at intersections. Additionally, the flexible mounting strap that fits aero seatposts gives it an edge for triathletes or aero-road bike users – a segment some other lights can’t cater to without extra adapters.
