There is vast a selection of lights for both bike, body, helmet and backpack. They range from small LED's to high powered centre stage lights. The lights you need depends on the riding you will be doing and good quality lights are essential throughout the winter and even summer months.
There are a few things to consider when buying your lights: * How they are powered - battery pack, USB rechargeable, batteries (disposable or rechargeable).
* How they are mounted - bolt on bracket mounts and quick release straps/bands.
* How visible they are - measured in lumens, which is the measure of light they produce; the higher the number, the brighter the light. Starting from 5 to 100 lumens for basic lights up to 1000 lumens plus for heavy-duty full beam spotlights.
* How many modes they have - variety of light display options from constant, various speeds of flashing, low and high beam, pulse and rapid.
