MEROCA Smart Bicycle Rear Light Auto Start/Stop Brake Sensing IPx6 Waterproof USB Charge cycling Tail Taillight Bike LED Lights Product Name: meroca 3rd generation smart bicycle tail lamp Material: main body aluminum alloy Color: Black Size: 16 * 6.5 * 4cm Weight: 85g Lamp beads: 20 imported bright lamp beads Endurance: 33.5 hours Waterproof: ipx6 waterproof grade : meroca Function: sensitive braking, close to zero misjudgment, built-in high-precision sensor, combined with depth algorithm, tail light can be detected quickly even if braking slightly. The horizontal angle is adaptive. The tail light can be corrected horizontally according to different angles of the sitting pole. In the uphill and downhill sections of riding, it can be corrected automatically to maintain the accuracy of braking at all times. Accurately move the start and stop. When the surrounding light is dark, the tail light will turn on immediately if you move the bike slightly. If you don't move the bike within 45 seconds, the tail light will turn off automatically. Sensitive light sense starts and stops. During riding, when the surrounding light is dark, the tail lamp will automatically light up. Where the light is bright, the tail lamp will automatically turn off after 30 seconds. Filter rocking and small bumps, and optimize the program algorithm. It can filter small rocking and small bumpy sections, but the brake light warning will still be activated if the pit and damping belt are too large. High brightness LED beads, Fresnel lens lampshade, lens designed by Fresnel principle, together with 20 high brightness LED beads, create high brightness, soft and non dazzling lighting effect. Automatic / manual mode switching, manual mode: manual control switch light, with brake sensing energy; Automatic mode: light sensing start and stop, mobile start and stop, inductive braking. In automatic mode, the tail light is off, and the brake sensing function is still available.
