Bike Lights

I cycle 6 miles a day & don’t need to use lights everyday, after using for 2 journeys the battery warning came on, I replaced batteries & after another few days the warning light came on again, not sure if faulty connection as batteries were brand new ..

One lights

Hag these lights over 15 month and used regularly! Batteries still good and the visibility is as good as from day one!

Not waterproof

The front light worked fine until it rained and got full of water inside - frying the electronics. The back light is good, although there is only ON or OFF

Easy to setup lights

I have to say that I recently I got the triban RC120 disc brake bike. It's beautiful but it can be difficult to find lights that will fit on the large diameter handlebars. These lights fit perfectly. The only disadvantage is that they could be removed fairly easily as they are not screwed on!

Very good

No Flash

Both front and rear lights doesn’t have flashing option. Even the ones you buy from poundland has this option. Otherwise lights are bright, but only due to ‘No Flash’ I am rating it badly. If you don’t need Flash Option, go for it these lights are value for money.

Lights with batteries

Bicycle lights with batteries. Exactly what I was looking for

Anti-human battery cover design

The battery cover of the front light is too easy to slip off even if you brake, meanwhile the battery cover of the back light is ridiculously tight and you will need a screw driver to open it, and it hurt my hand so badly for changing battery.


So happy

Faulty - drains the battery

I have had to change the front light batteries twice, despite only using for a maximum of one hour. Wouldn’t recommend.

Bike Lights.

A little expensive for the quality.

Thanks to feedback provided by cyclists and other road users (drivers, pedestrians, etc...), our design teams have defined optimum features linked to cyclists' visibility. With one purpose in mind: ensuring cyclists' safety.


LED brightness: - front LED light: 75 lumens, 35 lumens in ECO mode - rear LED light: 3 Lumens. Approved for road cycling in France and Germany (STVZO). Equipped with special lenses that focus the light so you can see in FRONT (at a speed of 10 mph) to avoid obstacles and be seen from behind within a 220° range.


3 x AAA front lights (included in the set) 2 x AA rear lights (included in the set) Also compatible with rechargeable batteries. To change the batteries, use a coin to open the rear light. For the front light, simply slide the cover back.

First use

To avoid draining the battery while in storage, the light is shipped with a small plastic tab that separates the batteries from the electronic component. Remember to remove this plastic tab before use. I



Product testing

Lab tests are conducted to validate the bike's components, including batteries, battery life, UV resistance, durability, etc. The final product is then tested to simulate the durability of the assembly over time. The light is fitted to a test bike to reproduce the vibrations of cycling on a road for several thousand cycles.
