GUB Expression Tail Light with Brake Sensor: USB rechargeable
Available Options

If you're a cyclist who values both safety and not fumbling around in the dark, the Expression Tail Light is your new best friend. Imagine this: you hit the brakes, and like magic (or, you know, smart engineering), the brake sensor kicks in, making you shine brighter than a disco ball—just when you need it most. Rain or shine, its waterproof design has got your back, because let's face it, the weather doesn't always play nice. And with a USB rechargeable battery, you're spared the horror of your light dying mid-ride (we've all been there). Whether you're tearing up mountain trails or just cruising around town, this light fits pretty much any bike and won't have you scratching your head over installation. Easy peasy.
