ROCKBROS Smart Bike Tail Light Brake Sensing Bicycle LED Rear Light 5 Modes

• SMART BRAKE SENSING & AUTO MODE (Max Exclusive) – When you brake, the light instantly boosts to high brightness for 2.5 seconds, clearly signaling deceleration to vehicles behind. In auto mode, built‑in light and vibration sensors handle everything: sleeps after 30s of stillness or under strong sunlight, wakes by vibration or low‑light conditions (tunnels, dusk) – saving battery while keeping you responsive at all times.
• 5 LIGHTING MODES + RECHARGEABLE 15 80H RUNTIME – Choose from red normal flash, red/blue alternating, colorful breathing, dual rapid strobe, or steady‑on. Powered by a rechargeable 300mAh battery, runtime ranges from 15 hours (brightest mode) up to 80 hours (economy mode). Type‑C port delivers a full charge in just 2 hours – perfect for daily commutes or all‑day weekend rides.
• REAL‑TIME BATTERY LEVEL INDICATOR – Four blue LED dots on the button clearly show remaining power in 25% increments (visible even in daylight). In auto mode, the indicators stay active, so you always know exactly when to recharge – no more unexpected shutdowns during your ride.
• WEATHERPROOF & TOOL‑FREE DUAL MOUNT – IPX5 rating protects against rain, splashes, and dust – reliable in sudden downpours or dusty trails. Comes with both saddle‑rail and seatpost brackets, so you can choose your preferred position. No tools required for installation; twist off easily to carry with you and deter theft when parked.
• PREMIUM ALLOY CONSTRUCTION & GENTLE OPTICS – Lightweight, scratch‑resistant aluminum alloy body is sturdy enough to survive drops and impacts. Advanced optical lens paired with COB LED delivers a wide, uniform beam that’s bright for visibility but non‑dazzling to followers – enhancing safety for everyone on the road.
