The Planet Bike Blinky Squared Ultra bike headlight is a compact and powerful front safety light designed for cyclists who demand reliability. Delivering 100 lumens, this compact 1.25-inch square headlight ensures you're visible to oncoming traffic. Powered by advanced chip-on-board technology, its 16 LEDs create a wide 180° beam, enhancing safety by providing clear visibility from the front and sides. Whether you're riding under the bright midday sun or navigating dark streets at night, the Blinky Squared Ultra offers modes tailored to every condition. The Superflash™ Day mode, designed for peak sunlight, provides visibility up to one mile away, ensuring safety even in broad daylight. For steady, reliable lighting, the High and Low modes offer consistent beams to light your way. Meanwhile, the Courtesy™ Mode and Steady Pop modes feature attention-grabbing flashing patterns for maximum visibility, keeping you safe in dim light or busy traffic conditions. Thanks to its mode memory function, the headlight remembers your last setting, so you can start each ride exactly how you left off. The Blinky Squared Ultra is fast-charging via USB-C and runs for up to 18 hours, depending on the mode. Tested to FL1 standards, it's also IP66-rated for dust and water resistance, ensuring durability in all conditions. Mounting is effortless with the stretch strap, securing the light snugly to any handlebar without tools.
