If you’re looking for a new rear light it might be tempting to splash out on something from well-known brands such as Lezyne or Exposure. However, the Guee Aero-X rear light shows that you don’t have to break the bank in search of a quality product.

For its sub-£25 price tag, the Guee Aero-X rear light is impressively bright. Guee doesn’t give a brightness figure with the light, but it should be more than bright enough to make sure that you’re seen by drivers, even when it’s just a bit gloomy rather than pitch black.
