Your bike lights have two uses: they illuminate the road at night and allow motorists and pedestrians to see you well. It is important to choose your lighting system based on the environment where you drive.
In the city
As the streets are usually pretty lit to allow you to see well, opt for lights which the primary function is to increase your visibility to motorists, pedestrians and other cyclists.
The lights that require relatively little energy are perfect for travel by city:
The battery led are light, compact and can be mounted to the handlebar, headset, saddle or rack. However, because of their limited light output, they are rather intended for occasional use.
Headlights crank will never leave you in the dark. They are recharged easily in a few turns of the crank and a battery life of 30 to 60 minutes. Their battery must be recharged regularly to remain in good working order (at least every two or three months if you do not use your lighthouse).
The lights working using AA or AAA batteries are brighter than the models button batteries or crank. They can be a good choice, ecological and economical, since they also accept rechargeable batteries. Ideal for the bike to work, they are bright enough to be seen even in sunny weather. It may be advantageous to use in flashing mode to stand in city traffic.
Plan to fix two lights at the front and the back of your bike: this will reduce the risk of running out of batteries along the way and you can make them shine out way, in mode flashing, to be really visible at all times with motorists. Wearing an extra beacon on your helmet, you can also inform motorists who do not seem to have seen you. However, be sure to use a low intensity light and make considerate: in addition to being rude, blind a road user is illegal and unsafe.
On the trails
When you ride there where there are no street lights, you must provide their own lighting. The light output you need increases with speed and the level of difficulty of the trails. A system of powerful lighting, offering a light beam both wide and long range, will allow you to have the necessary reaction time when you encounter obstacles.
Many cyclists use two lighting systems: one to the handlebar and one on the helmet.
For handlebar headlights must produce a luminous flux of several hundreds of lumens. It is recommended to use with batteries high performance lithium-ion designed for smart Chargers that optimize their life expectancy. These headlights project a narrow beam of light that shines to the front, which leaves a large part of your field of vision in the dark. However, the shadows they project you can more easily identify the holes, rocks and roots.
Lighthouses that are attached to the headphones don’t produce shadows that help see the obstacles, since the axis of the light beam always follows your gaze. However, they illuminate everything you look at.
If you leave your side lights during the summer season, or if you store your bike in winter, don’t forget to recharge your batteries and batteries before storing. You can damage them, leaving them without charge for an extended period. It is also advisable to recharge a few times an hour or two when not in use. Furthermore, make it a habit to remove the disposable alkaline batteries in your lights before storing: these batteries are sometimes leaks, which could damage your equipment.
