Proper bike lights make your cycling trips much safer. First of all, you'll be able to see more in the dark. But perhaps more importantly, other road users will be able to see you as well. Depending on where you cycle, you can choose from different types of bike lights. A headlight or tail light for a city bike doesn't need to be as bright as a light for a road biker. Besides bike lights for nighttime, day bike lights are becoming increasingly popular. This will ensure you're highly visible during the day as a mountain biker or road biker.
