Front Light Completely Fell apart!!

Been using these Lights for a couple of weeks with no issues - lights where a good enough quality for my evening commute home. Went out for a cycle at the weekend and the front light completely fell out of the casing while riding. Not a very good quality light if it cant withstand a couple of weeks of daily road use!!

Dear Sir,
I'm sorry to read that these lights fell apart. Not acceptable of course.
Could you kindly return them to us for a refund or and exchange.

poor design

I bought this set of lights instore and whilst the brightness is fine I find I cannot turn the rear light off without having to unclip it and take it apart which is not very useful.

Indeed, it sounds as if your rear light is faulty. please return it to us and we will issue you with a refund or an exchange.

Average lights

Bought these lights as I was unsure what to buy, they do what they are supposed to do although I can't see the rubber bands lasting, great light not the brightest but they are good as an additional light

poor quality straps

My rear light strap broke after second use. Not a major problem as you can easily use a regular elastic band to replace it. Then the front light strap snapped as well. That was with less than 10 times use. Now I haven't figured out how to replace the broken strap.

Hi Sharon,

I'm sorry to hear that the straps have snapped on both front & rear lights. If you still have the receipts you can return the product for an exchange or refund if it is within the 2 year warranty.

300 Bike Front/Rear Lighting Set

Bought this 300 Bike Front/Rear Lighting Set for my Grandsons bike, so easy to fit and well made, only negative is that there is not a flash mode on this lighting set otherwise great value.

Bike lights

These lights are exactly what I wanted, being suitable for dark early mornings, simple to use and fit, and a easonable price.

Also came with batteries was a big plus

Does the job

This is not the best light but for the price I don't really feel I should complain. The back light is tricky to turn on. I often have to press it a number of times. I like the look and style of the light, it's just not as bright as I require

If only looks mattered

Smart looking. Strap came apart within 5 months, in spite of being permanently mounted on the bike. Very weak light, less than stated. Back light is bright.

Clamping is some difficult ..

Please improve brightness of light

Poor Quality front light.

Had purchased it online & fixed the lights on my bicycle after nearly 1.5 months. Within 1 month of use the strap of the front light has already developed large cracks & is about to get totally damaged, which will render the light totally useless.
