Spring is here and long summer days are just around the corner. You may be thinking it's time for bike lights to be retired until next winter, but for me, using the best bike lights is an all-year-round riding requirement – enhancing your visibility to other road users even in daylight riding.

The SEEMEE 300 has a host of interesting features that make it a great choice for anyone looking for a top-rated rear bike light.

It has one of the best battery run times of any light on the market, at over 200 hours. The superb battery life powers two LEDs maxing out at 300 lumens and combines with the angled lenses to boost visibility.

The smart auto-dim feature helps prolong the battery life and adjusts brightness to suit the ambient light conditions. The main feature I like is the LED downward light which projects an extra beam directly onto the ground below you and massively increases visibility.

If you're after a front light cycling deal, then the Exposure Strada MK12 SB is one of the best around with loads of power and a huge battery life. The Knog Blinder 900 is also at one of its lowest prices and is a more budget-friendly choice.
