USB-rechargeable bike light set with a built-in 650mAh lithium battery for each light. IPX4 splash resistance and silicone straps allow tool-free mounting to bars, posts and helmets.


Bright, adaptable visibility – thanks to four light mode options

A one-touch switch cycles between full brightness, half brightness, fast flashing and slow flashing modes for both headlight and taillight. Modes let the LEDs run at different output levels or flash patterns to suit conditions.

Choose high output for maximum visibility on dark roads or flashing modes to attract attention in busy traffic, helping other road users spot the bike sooner.

Long, rechargeable runtime – thanks to built-in 650mAh lithium battery

Each light contains a 650mAh rechargeable lithium battery and comes with USB charging cables for easy recharging from a power bank, laptop or USB wall charger. The lights are USB rechargeable rather than using disposable cells.

Recharge from typical USB sources between rides, avoiding single-use batteries and keeping the lights ready for regular commutes and short trips.

Secure, tool-free mounting – with silicone mount straps

Silicone straps feature two openings and stretch to fit a wide range of seat posts, handlebars, seat risers, backpacks and helmets. Straps fasten tightly to hold lights in place without tools.

Attach and remove lights in seconds for quick transfers between bike and bag, or to take them inside overnight, while retaining a firm hold during bumpy rides.
