A rear light that tells the driver behind you when you're slowing down. Its smart sensor lights it up automatically as you brake, the same signal a car gives, so you're not just seen on dark lanes and busy roads, you're understood.

At 37.6g you won't notice it on the bike. The people behind you will.

Why it's worth swapping your old rear light for

• A brake signal that runs itself: the smart sensor switches it on automatically when you brake.
• Bright and easy to spot: COB lamp beads, 49 on the red version and 61 on the multicolour one.
• Rain is fine: rated IPX4 for rain and splashes.
• Light but solid: aluminium alloy and PC, 37.6g in all.
• Built-in battery: 400mAh lithium.

Choose your light

• Red: a single-colour light with 49 COB beads.
• Colorful: a multicolour display with 61 COB beads, for a bike that really stands out.
