  • Automatic on/off
  • Anti-theft alarm

You lock your bike outside a coffee shop and walk away. Minutes later, your phone buzzes with a motion alert. The NEW Bicycle Alarm Taillight doesn't just light up your ride—it protects it. Its built-in burglar alarm triggers a loud siren the moment someone touches your bike, giving you peace of mind while you're away.

Beyond security, this smart light keeps you visible. The auto brake sensing feature detects when you slow down and automatically brightens the tail light, so drivers see you stopping. USB rechargeable and waterproof, it's built for daily commutes. Mount it on your seatpost and ride with confidence, knowing your bike is safe and you're seen.
