Safety for everyone
Feedback from cyclists and other road users (drivers, pedestrians, etc.,) led to optimum features for cyclists’ visibility. With one purpose in mind: the cyclists’ safety. Equipped with a special lens, this bike light ensures you are seen at a 220 degree angle! And especially an angled light beam. For the same power, approved lighting makes you more visible than non-approved lights.
Stick it where you want!
Whether it's strapped to your seat post or clipped to your helmet, the RL 510 light adapts to your every need. Its clip lets you attach it to any B'Twin helmet or other compatible bike accessory.
USB charger
The battery warning light comes on 30 minutes before your lights are going to run out of power. The warning light flashes red. It takes 2 hours to fully recharge via its micro USB cable when plugged into a computer or 5V 500mAh adaptor.
Look after your lights
If you don't use your product for a long time, the LiPo battery might shut itself down. Remember to charge it every 3-4 months when not in use. In addition, avoid leaving your lights somewhere cold for long periods. LiPo batteries don't like the cold as it makes them lose capacity, so they won't last as long.
A long life
Your product has been designed for a minimum of 2500 hours of use—that's 40,000 km (25,000 mi) for the average cyclist (commuters and sport cyclists). If needed, spare parts for this product are available from the after-sales service and on our website.
Technical specifications
LiPo battery capacity: 320 mAh (500 cycles guaranteed) LED light power: 3 lumens. Sold with a micro USB cable and mount.

Light came off of holder on second ride. This was a road ride… not MTB. Pretty annoying it can drop off the bike so easily.

Great light, though I wish it had a flash mode (I thought it did when I purchased it so I was surprised and had to recheck the description online, which states non flashing). Easily charges and operates and easily attaches to my seat bag.

Good price for a light that can clip to cycle helmet or bike, so important to be seen on any bike ride

Une bonne idée, adapté au casque que j'ai acheté (sur lequel il se fixe) il permet d'être vu. Autonomie à voir (je ne l'ai pas encore vraiment utilisé, les journées sont longues actuellement)

Contrairement à ce que laissait penser sa forme , l'éclairage ne comporte qu'une seule lumière au centre et n'est pas plus visible que l'Elops SL510 vendu 10,99. L'obturateur caoutchouc sensé fermer la prise USB a disparu lors de la première sortie ! Autonomie parfaite , plus
de 8h00. Inclinaison idéale pour l'angle du tube de selle. Fabrication française , un bon point.

La charge tient assez longtemps, c'est simple à recharger. ça s'accroche simplement à l'arrière du casque ou sur le sac.
