It is against the law to ride a bike on the road in the dark without lights for good reason. There is nothing more important you can do to make yourself visible on the road than having a high quality set of front and rear lights.
Many different options are available, from small watch battery powered safety-lights, to huge Cree LED options that are rechargeable, have multiple modes, and are bright enough to rival the headlights on an HGV.
Your choice should be dependent on your personal circumstances; ensure you have lights that are suitable for when and where you are riding your bike for optimum safety.
There are a wide variety of cycle lights available for both the front and rear of your bike.
