Basic Principle. The basic concept behind a battery-free bicycle light is to
use the motion of the bicycle wheel to generate electricity
. As the wheel rotates, it turns a dynamo of some kind, which acts as a generator. The dynamo produces an electric current that is then delivered to the lights.

What is a good lumen for bike light?
What is a Good Brightness for a Bike Light? Cyclists travelling through well-lit areas should aim for a
100- or 200- lumen

Should I use bike lights during the day?
Although the law only requires that bicycle lights be used during the defined hours of darkness,
“being seen” is just as important during the day as it is at night.
Should my bike lights flash?
A 2005 amendment to the The Road Vehicles Lighting (Amendment) Regulations made it legal to use flashing lights on a bicycle in the UK
. The regulations state that, if you choose to use flashing lights, they must flash at a frequency between 1-4hz, which is between one and four flashes per second.
Are flashing bike lights safer?
The jury is still out on whether it’s safer to run flashing or steady lights –
a flashing light can distort depth perception
and a steady light can be easily lost in a sea of other distracting lights. The safest thing to do is run both, perhaps using a helmet-mounted light for the rear flashing LED.
How bright is too bright for bike lights?
Anything more powerful than
200 lumens
will dazzle some on-comers. In the pitch dark or in very poor lighting conditions it’s best to avoid using flashing lights for several reasons. A steady 200 lumen or brighter light can easily be spotted from far away, and if it’s angled properly, it doesn’t blind anyone.
Which LED light is best for bike?

; indicating that the permanent bicycle running light significantly improves traffic safety for cyclists.
What angle should bike lights be?
What’s your aim? Since bike lamps cannot (usually) be dipped, and are not fixed in the vehicle, the standards for bike lamps have to make assumptions about how the lamp is likely to be aimed. They generally assume the brightest spot in the beam will be aimed downwards at an angle of
3.5 degrees
.
How do you turn on bike reflectors?
Hold the light as near as possible to your eye level at the side of your head
for best results. Alternately you may use a car to see how its headlights reflect back to the driver. Adding reflectors to supplement your lights is an easy, cost-effective way to make your bike more visible in the dark.
How do you turn on a bike dynamo?
The standard dynamo runs at the side of the tyre. To switch the light on and off the dynamo is switched so that it runs on the tyre or as the case may be, pulled away from the tyre to turn it off. Some dynamos have a button or lever, on many bicycles one must
