High-Visibility Ebike Taillight With Smart Brake Sensing The Supernova TL3 Pro is a rack-mounted ebike taillight built to make your braking and emergency stops unmistakably clear. A high-precision 3-axis sensor inside the light detects deceleration and instantly boosts output, so following traffic gets a bright, obvious brake signal without any special brake lever wiring. Behind the slim housing, 32 LEDs fire through a finely tuned light guide for a bright, homogeneous signature that is easy to pick out from a distance and from the side. An integrated emergency strobe ramps up the warning effect during hard stops, and standard 50 mm rack mounting plus a long cable make it straightforward to integrate with most 6–12 V ebike systems. Smart Details That Count Sensor-controlled brake light uses a 3-axis accelerometer, so no brake-lever connection is required Taillight output jumps from 6 cd to 60 cd under braking, making the signal nearly 70% brighter than the running light level Array of 32 LEDs behind a high-tech diffusion light guide creates a bright, even signature with excellent side visibility Emergency strobe function adds a pulsing warning pattern during hard braking, similar to automotive brake alerts Designed for ebikes, with wide compatibility across 6–12 V light outputs on common mid-drive systems Long 2 m cable with open ends gives plenty of length for clean routing on most cargo and city ebikes Supernova build quality with compact housing and low weight for a tidy, durable rear rack install
