As the nights draw in the chances are you'll be commuting in the dark. An appropriate set of lights is essential for autumn and winter cycling. Lights that have flashing modes help make sure you stand out and will distinguish you as a cyclist to other road users. This video is for the A and C Line bike. The front light fits in the same way on the T and P Line, but the rear light shown is not compatible with the T Line or P Line saddle.
