BRAKE-SENSING REAR BIKE LIGHT WITH ACCELEROMETER — GETS BRIGHTER WHEN YOU BRAKE: Tailgator's accelerometer detects rapid deceleration and triggers a brighter brake burst, giving drivers behind you a dedicated "slowing" signal beyond a standard constant blink. No app, no wiring, no remote. Mount to seatpost and the light does the rest. Note: gradual slowing may not trigger the burst — normal behavior that prevents false triggers and extends battery life. 300-LUMEN BRAKE BURST, WIDE ANGLE, BUILT FOR EVERY BIKE TYPE: Three LEDs deliver up to 300 lumens during the brake burst for strong rear visibility in daylight and at night. Wide-angle LED array puts light behind you and to the sides. Built-in ambient light sensor auto-adjusts output to riding conditions. Road, gravel, mountain, commuter, e-bike, hybrid: wherever rear visibility and a clear braking signal matter — city streets, open roads, pre-dawn commutes, evening loops. 5 LIGHT MODES — THREE WITH BRAKE SENSING, TWO WITHOUT: Moderate flash, fast flash, and pulsing strobe all include brake-sensing activation — the light brightens on rapid deceleration in each of these modes. Steady flash and steady dim provide constant visibility output without sensing, for rides where predictable output matters more than automatic activation. Single button cycles through all five modes; no apps or settings required. MICRO-USB RECHARGEABLE, UP TO 60 HOURS, AUTO-SLEEP: Charges in approximately 2.5 hours with the included Micro USB Charging Cable. Runtime: up to 60 hours on select low-output modes, as low as 8 hours in high-output brake-burst mode — actual runtime depends on mode and how often the burst fires. Auto-sleep mode activates when stationary to conserve battery between rides, at café stops, and during storage.

Tailgator Brake-Sensing Rear Bike Light — What Makes It Different Standard rear bike lights blink. Every mode, every speed, every situation — same rate whether you're cruising or stopping hard. Tailgator adds a brake burst: a brighter flash triggered by the accelerometer inside the light when it detects rapid deceleration. Drivers behind you see something different when you brake. Not just a blink, but a signal. That's what Tailgator's patent-pending accelerometer does — detect deceleration and trigger up to 300 lumens, instantly, automatically. No app. No Bluetooth. No lever wiring. Specs: up to 300 lumens at brake burst / three ultra-bright LEDs / wide-angle output / built-in ambient light sensor (auto-adjusts to conditions) / IPX5 water resistant / five light modes (three with brake sensing, two without) / 8–60 hours runtime / approximately 2.5-hour full charge via Micro USB / Universal Seat Mount with tool-free installation. Compatible with road, gravel, mountain, commuter, e-bike, and hybrid bikes. Multiple mounting positions — seatpost is optimal for sensing, but if blocked, alternative mounting options allow placement almost anywhere on the bike. The reason Tailgator is priced at a premium: patent-pending accelerometer technology, 300-lumen brake burst (many brake-sensing alternatives don't specify lumens), and a lifetime warranty with no expiration, no conditions, and no fine print. If it ever fails for any reason, Tailgator replaces it. Makes a practical gift for cyclists who ride in traffic — ships complete with everything needed to install in minutes. What's Included: Tailgator Brake Light / Universal Seat Mount / Universal Adjustable Band / Micro USB Charging Cable / Quick Start Guide Shopper Q&A Q: Does the brake burst fire every time I slow down? A: On rapid deceleration only. Gradual slowing may not trigger it — by design, to prevent constant false activation. Q: Where should I mount it for best sensing? A: Rear seatpost, mounted firmly so it doesn't shift during riding. Seatpost is the recommended location for most consistent sensing. Q: What if a rack or seat bag blocks my seatpost? A: Multiple alternative mounting positions are included — you can mount Tailgator almost anywhere on the bike. Make sure it's firmly attached wherever you place it. Q: How do I remove it for charging? A: Press the tab in, slide the light off the base (the base stays strapped to the post), and plug in with the Micro USB cable. Do not force or twist — it slides off cleanly. Q: Is it USB-C? A: Micro USB. Included cable. Approximately 2.5-hour full charge. Q: How long does the battery last? A: 8–60 hours depending on mode and brake burst frequency. Auto-sleep mode conserves battery when the bike is stationary. Q: Is it
