How we chose
We filtered for low price, practical commuting use, simple mounting and products that make sense as either a main town setup or a backup.
- Does it solve the rider problem without adding faff?
- Will it fit the bikes and riders most likely to need it?
- Is the price sensible for a commuter or family rider?
- Are the weak points clear before you click through?
What not to buy
Avoid claiming a tiny budget light is suitable for fast unlit lanes. If there are no streetlights, spend more on a better beam.
FAQs
Are cheap bike lights legal?
They can be, provided you use a white front light and red rear light after dark. The bigger question is whether they are bright and reliable enough for your route.
Are budget bike lights waterproof?
Some are water-resistant, but always close USB port covers properly and dry lights before charging after heavy rain.
