ROCKBROS Q4 Multi Colour Rear Light

Be seen differently. Be seen safely.

The ROCKBROS Q4 stands out from every other tail light on the rack — literally. With red, blue, and purple multi-colour LED modes, smart brake sensing, auto on/off vibration detection, and IPX6 waterproofing, it delivers serious visibility with serious style. Whether you're commuting through traffic or riding after dark, the Q4 keeps you seen.

5 Modes Including Multi-Colour Red/Blue/Purple Four flashing modes cover slow red flash, fast red strobe, three-colour breathing, and three-colour alternating strobe: plus a steady red constant mode. The multi-colour modes make you stand out in traffic in a way a standard red flasher simply doesn't.

COB LED Lamp Beads — Bright Without Dazzling Five COB LED lamp beads produce light that is bright and soft — the PC optical lens keeps the output powerful but not blinding to riders or drivers directly behind you. Visible from a distance without being aggressive up close.

IPX6 Waterproof The IPX6 waterproof design performs well in sudden rain and meets daily cycling needs — built for year-round commuters and riders who don't check the forecast before heading out.

Tool-Free Saddle & Seatpost Mount Easy to install with no extra tools needed, and compact enough to take with you so it doesn't get stolen. On in seconds, off just as fast for charging or storage.

USB Rechargeable Charges via standard USB — plug it into any wall charger, laptop, or power bank. No disposable batteries, no mid-ride surprises.

Perfect For

• Commuters in traffic who need active brake signalling
• Night riders wanting maximum rear visibility
• Riders who want to stand out with multi-colour modes
• Anyone who wants a set-and-forget light that turns itself on and off
