About this product

A rear bike light with 5 red LEDs and twin laser lines, built to improve visibility when riding in darker conditions. Battery powered and waterproof, it gives a clear rear warning light with a choice of 7 flashing modes for commuting, leisure rides and general road use.

Used for cycling in low light, early mornings, evenings and poor weather, this light helps make the back of the bike more noticeable to other road users. The added laser lines project onto the road surface to give a wider visible presence behind the bike, which can be useful for commuting, winter riding and wet-weather journeys where visibility matters more.

The 5 red LEDs provide the main rear light, while the 2 laser lights add an extra visual guide behind the bike. With 7 flashing modes, you can choose a setting that suits the conditions or your riding preference. Waterproof construction makes it suitable for foggy and wet weather, and the battery powered design keeps fitting and replacement straightforward. Supplied with 2 x AAA batteries included, it has a stated working time of 9 to 36 hours depending on use, which is useful for regular riding without constant battery changes.
