Rider’s Guide to the Best Bike Lights

Bike lights are an important safety gadget for cyclists, providing visibility (and be visible) to other road users and illuminating the path ahead. There are many different types of bicycle lights available, from basic LED lights to high-powered lights that can illuminate the road ahead for several hundred meters. Choosing the right bicycle light depends on factors such as the type of cycling you do, the time of day you ride, and the lighting conditions in your area.

History of Bicycle Lights

Have a look at the unique and interesting history of the of bicycle lights, and how it evolved through the centures.

Candles and Lanterns

The first bicycle lights were candles placed in lanterns attached to the front of the bicycle. These lanterns were typically made of metal and had glass panes. They were fueled by oil or gas, and had a wick that was lit to provide light. These were usually held by the rider as he or she rode the bike, making the ride a precarious one.

The main problem with these lanterns was that they didn’t provide very much light and they were quite fragile. They also required constant refilling of the fuel and maintenance. Imagine a fall that breaks the glass and spills the oil in the middle of a ride!


After the lantern lights, the next evolution in bicycle lights was the acetylene lamp. Acetylene lamps were invented in the late 1800’s and they were much brighter than the earlier lantern lights. They were also less fragile and required less maintenance. Acetylene lamps worked by burning acetylene gas, which was produced by mixing calcium carbide with water in a generator that was mounted on the bicycle. This type of lamp was used for many years, but the main problem was that the gas was highly flammable, and the generator required constant maintenance.

Incandescent Light

It wasn’t until the invention of the incandescent light bulb in the late 19th century that bicycle lights began to really evolve. Incandescent bulbs work by passing an electric current through a wire filament, causing it to heat up and emit light. These lights were used on bicycles for many years, particularly during the early to mid-20th century. On bicycles this light typically consisted of a bulb mounted in a reflector, which was attached to the bicycle’s frame, handlebars, or fenders. The power source for these lights was usually dry cells or other disposable batteries.

While incandescent lights provided illumination, they had some limitations. They consumed more power compared to modern LED lights, resulting in shorter battery life. Additionally, incandescent lights produced relatively dimmer light output and were more prone to filament breakage due to the vibrations experienced during cycling.

Dynamo Powered

Dynamo-powered bicycle lights were introduced in the late 19th century, around the 1870s to 1890s. The development of dynamo-powered lights coincided with the popularity of bicycles as a means of transportation. Dynamo lights, also known as generator lights, relied on a dynamo or generator attached to the bicycle’s wheel. As the wheel turned, it drove the dynamo, which generated electricity to power the lights. These early dynamo lights typically used incandescent bulbs.

The introduction of dynamo-powered lights was a significant advancement at the time, as it provided a self-sustaining lighting solution for bicycles. Riders no longer had to rely on external light sources such as lanterns or oil lamps. Instead, the motion of the bicycle itself generated the electricity needed to power the lights.

Dynamo lights remained a popular choice for bicycle lighting for several decades until the development of battery-powered lights and later LED lights, which offered greater convenience, longer battery life, and improved brightness. However, dynamo lights are still used today, particularly in certain cycling disciplines like touring and commuting, where riders prefer a reliable and self-sustaining lighting system.

Halogen Lights

In the 20th century, with the advent of new technologies such as halogen, the prevalence of bike lights increased. Halogen lights were a significant improvement over incandescent lights. They were about twice as bright and had a longer lifespan.
Halogen lights were commonly used in bicycles during the 1980s and 1990s. Halogen bulbs offered brighter and whiter light compared to traditional incandescent bulbs, making them a popular choice for bicycle lights at that time. These lights typically used a halogen bulb combined with a reflector to concentrate and direct the light beam. Halogen lights were often powered by batteries, either disposable or rechargeable, and were known for their improved visibility and longer battery life compared to earlier lighting technologies. However, with the advent of LED technology and its numerous advantages, such as higher energy efficiency and longer lifespan, halogen lights have become less common in modern bicycle lighting systems.

LED Lights and its variations

The development of light-emitting diodes (LEDs) revolutionized bicycle lighting. LEDs are small, energy-efficient, and provide bright illumination. LED lights started replacing traditional incandescent bulbs in the late 20th century, offering longer battery life and increased visibility, with various charging mechanisms and variations in uses.

USB Rechargeable Lights: USB rechargeable lights have gained popularity due to their convenience. These lights feature built-in rechargeable batteries that can be easily charged using a USB cable connected to a power source. USB rechargeable lights eliminate the need for disposable batteries, offering a more sustainable solution.

Smart Lights: Recent advancements have introduced smart features to bicycle lights. Smart lights can be connected to smartphones or other devices via Bluetooth or Wi-Fi. They often include features like automatic brightness adjustment, turn signals, and connectivity with cycling apps to provide additional safety and functionality.

High-Visibility Lights: In recent years, high-visibility lights have become popular. These lights utilize powerful LEDs to emit extremely bright light, making cyclists more visible to other road users, especially in low-light conditions. High-visibility lights often offer various light modes, including flashing patterns, to attract attention and enhance safety.

Integrated Lights: Bicycle manufacturers began integrating lights into the design of the bikes. These lights are often built into the frame, handlebars, or seat post, providing a sleek and streamlined appearance. Integrated lights are typically battery-powered or rechargeable via USB.

Lights on helmets: Advancements in LED and battery technologies has led to the helmet based lights as another option for bike riders.

Battery Technology

Before the invention of rechargeable batteries, as we saw in the section above, cyclists had to keep replacing the fuels (oil, acetylene) and batteries in their bicycle lights. Rechargeable batteries changed that. These allowed cyclists to recharge their lights, rather than having to buy new batteries all the time. This not only saved cyclists money, but it also reduced waste. In recent years, battery technology has evolved even further, with the development of lithium-ion batteries. These batteries are smaller, lighter, and last longer than previous types of rechargeable batteries.

How to Choose a Bike LIght

Choosing bike lights depends on several factors, including the type of riding you do, and the conditions you typically ride in. Here are some key considerations to help you choose the right bike lights:

  1. Brightness: Look for lights that offer sufficient brightness to make you visible to others and illuminate the road ahead. The brightness of a light is measured in lumens. Rear lights usually range from 20 to 100 lumens, while front lights can range from 100 to 1000+ lumens.
  2. Beam pattern: Consider the beam pattern of the light. Some lights have a focused beam that helps you see far ahead, while others have a wider beam that increases visibility from the sides. For urban riding, a light with a wider beam is usually more suitable.

    To makes sure that the brightness and beam pattern do blind the person coming towards you in the other direction, adjust the angle and make it pointed towards the ground.

  3. Mounting options: Check if the lights come with suitable mounting options for your bike. Most lights offer versatile mounting systems that can be attached to handlebars, seat posts, helmets, or clothing. Ensure the mounting mechanism is secure for your type of riding.
  4. Battery life and charging: Evaluate the battery life of the lights. Longer battery life is essential for longer rides or commutes. Consider whether the lights use replaceable batteries or are rechargeable via USB. Rechargeable lights are generally more convenient and cost-effective in the long run.
