BIKIGHT LIG019 Smart Sensoring Brake Bike Taillight: Brake sensor activation
Ever been cycling and wished your bike could just get you? Meet the BIKIGHT Smart Sensoring Brake Bike Taillight—your new safety sidekick. It's got this nifty trick where it flashes super bright for 3 seconds the moment you hit the brakes (because sometimes, you need to stop on a dime). And if things go sideways (literally), it switches to a special flash mode that's like shouting, 'Hey, I'm here!' to everyone around.
But wait, there's more (and no, this isn't an infomercial). It's smart enough to know when it's dark out, thanks to its built-in light sensor, so it only bothers you when it's actually useful. Plus, it laughs in the face of rain with its IP66 waterproof rating, and its 1400mAh battery? Charges via USB because it's 2023, after all.
What's in the box? Just the taillight and a strap to slap it on your bike. Fair warning: if your seat tube's 28.6mm thick, you might need to play around a bit to get it just right. But hey, no one said safety was effortless.
