TAILGATOR Brake-Sensing Bike Tail Light (Accelerometer) – 300 Lumen Brake Burst Rear Light – USB Rechargeable (Micro-USB) – 5 Modes – Wide-Angle Visibility – Seatpost Mount

TAILGATOR Brake-Sensing Bike Tail Light is built for riders who want strong rear visibility plus a clearer signal when they slow down. A built-in accelerometer detects rapid deceleration and triggers a brighter brake burst to help traffic behind you recognize that you’re slowing—without an app, remote, or wiring.Brake sensing (expectation): The brake burst is designed to activate during rapid deceleration. Gentle slowing may not trigger the brake burst, which helps prevent constant activation and supports battery life.Quick SpecsUp to 300 lumens during brake burstFive light settings (includes non-brake modes)USB rechargeable (micro-USB) – cable includedUp to 60 hours depending on mode and braking eventsWater-resistant ABS housingSeatpost strap mountLifetime warrantyWhat’s IncludedTailgator Rear Tail Brake LightPlastic attachment deviceBand to secure to seatpostUSB charging cord (micro-USB)Instruction manualQ&AQ: Does it brake-flash every time I slow down? A: It’s designed to trigger on rapid deceleration. Gentle slowing may not activate the brake burst.Q: Where should I mount it for best brake sensing? A: Mount it on the rear of your seatpost for the most consistent brake sensing.Q: Will it work if I have a rack or seat bag? A: If your seatpost is blocked by a rack/seat bag, mounting options may be limited. If the light is not rigidly mounted and shifts, brake sensing may be less consistent.Q: Is it USB-C? A: Charging is micro-USB using the included cable.Q: How long does the battery last? A: Up to 60 hours depending on mode and how often the brake burst triggers.Q: Is it waterproof? A: It is water resistant for typical riding in rain/splashes.Q: What modes are included? A: Five modes: moderate back-and-forth flashing, fast back-and-forth flashing, pulsing/strobe, steady flash (no braking action), and steady dim (no braking action).Q: What if it stops working? A: It is backed by a lifetime warranty.

• BRAKE-SENSING REAR LIGHT (ACCELEROMETER) – Tailgator detects rapid deceleration and triggers a brighter brake burst so drivers and riders behind you can recognize when you’re slowing. Gentle slowing may not activate the brake burst—this is normal and helps prevent constant triggering.
• 300-LUMEN BRAKE BURST + HIGH VISIBILITY – Up to 300 lumens during the brake burst for a strong “I’m slowing” signal. Designed to help you stay noticeable day or night for commuting, road, gravel, and trail rides.
• 5 MODES FOR DIFFERENT RIDES – Choose the pattern that fits your conditions: moderate back-and-forth flash, fast back-and-forth flash, pulsing/strobe, steady flash (no braking action), and steady dim (no braking action).
• USB RECHARGEABLE (micro-USB) + LONG RUNTIME – Recharge with the included micro-USB cable. Runtime varies by mode and braking events, with up to 60 hours on select settings. Auto-sleep helps conserve power when not in use.
• SEATPOST MOUNT + FIT NOTES – Tool-free strap mount is designed for seatpost installation for best stability and brake-sensing performance. If your seatpost is blocked by a rack/seat bag, mounting options may be limited and brake sensing may be less consistent if the light shifts. Backed by a lifetime warranty.
• VERSATILE FOR MOST BIKE TYPES – Tailgator is built for everyday riding across road, gravel, mountain, commuter, e-bikes, and hybrid/fitness bikes. Ideal for city streets, bike paths, and light trail use—wherever added rear visibility and a clear “braking” signal helps you stay seen.
