When you brake, the light automatically increases its flash intensity to signal drivers behind you — just like a car’s brake light.\u003c\/p\u003e\u003ch3\u003eQ: What does the intelligent light sensor do?\u003c\/h3\u003e\u003cp\u003eA: The ambient light sensor monitors surrounding brightness. It automatically activates the tail light in low-light or dark conditions and reduces output in bright daylight, extending battery life and ensuring appropriate visibility at all times.\u003c\/p\u003e\u003ch3\u003eQ: What is vibration wake-up?\u003c\/h3\u003e\u003cp\u003eA: The vibration sensor detects movement when you pick up or start riding your bike. The light powers on automatically — and enters sleep mode when the bike is stationary for a set period, conserving battery without any manual input.\u003c\/p\u003e\u003ch3\u003eQ: How long does the battery last?\u003c\/h3\u003e\u003cp\u003eA: The \u003cstrong\u003e3.7V 600mAh lithium battery\u003c\/strong\u003e provides up to \u003cstrong\u003e70 hours\u003c\/strong\u003e of runtime depending on the mode used. Flash modes consume less power than steady-on modes.\u003c\/p\u003e\u003ch3\u003eQ: How do I charge it?\u003c\/h3\u003e\u003cp\u003eA: Charge via the \u003cstrong\u003eUSB-C port\u003c\/strong\u003e using any standard USB-C cable. The reversible connector makes it quick and easy — no fumbling with orientation.\u003c\/p\u003e\u003ch3\u003eQ: Is IP66 waterproof enough for heavy rain?\u003c\/h3\u003e\u003cp\u003eA: Yes. \u003cstrong\u003eIP66\u003c\/strong\u003e is a professional-grade waterproof rating that protects against powerful water jets from any direction — more than sufficient for heavy rain, puddle splashes, and wet road conditions.\u003c\/p\u003e\u003ch3\u003eQ: What is the beam angle and why does it matter?\u003c\/h3\u003e\u003cp\u003eA: The \u003cstrong\u003e220° wide-angle beam\u003c\/strong\u003e means drivers, pedestrians, and other cyclists can see your light from almost any angle behind and to the side of you — significantly improving your safety at intersections and when changing lanes.\u003c\/p\u003e\u003ch3\u003eQ: What are the dimensions of the light?\u003c\/h3\u003e\u003cp\u003eA: The tail light measures \u003cstrong\u003e30 × 41 × 26 mm\u003c\/strong\u003e — compact and lightweight, it mounts discreetly to your seat post without adding bulk.\u003c\/p\u003e","brand":"TTpen","offers":[{"title":"Default Title","offer_id":55483724235057,"sku":null,"price":16.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/2630\/3793\/files\/Smart-Brake-Sensing-Bicycle-Tail-Light.jpg?v=1785229595","url":"https:\/\/www.ttpen.com\/products\/smart-brake-sensing-bicycle-tail-light-52-lumens-220-wide-angle-rechargeable-ip66","provider":"TTpen","version":"1.0","type":"link"}
