Frequently Asked Questions (FAQs)

What are the best lights for bikes?

If you bike a lot at night or in the early hours of the morning, you know how vital the right lights are. It is crucial to have the right lighting equipment or you could end up running into trouble.

Most bike lights fall into two main categories: steady or flashing. Each kind has its share of pros and cons, so it comes down mostly to a personal preference.

Bicycle lights provide safety for you, other drivers, and road users. Some states require front and rear bike lights for night riding, so it is best to get into the habit of using them.

The best bike lights for the money are the ones that are easy to move around and easy to see. They should be able to illuminate the road ahead and keep you visible to other drivers. Whether commuting to work or just enjoying the night air, you must be prepared with the right bike lights.

In our opinion, Cygolite Metro Plus 800 USB is the best headlight for cycling.

How many lumens do I need for cycling?

Helmet lights typically include between 70 to 100 lumens, while handlebar lights range from 200 to 500; some even have as much as 1600 lumens. If you are cycling fast with high gear ratios, you will need more lumens.

Price is also a factor, as you’d expect helmet lights to cost less than handlebar lights. This is because handlebar lights need a stronger bulb due to the distance, and they perform better in wet conditions.

However, it is best not to be fooled with the numbers, as too many lumens do not necessarily mean the light is brighter. Instead, you should look for quality light that can reach and scatter light in all directions.

Some lights have specific settings for cycling at night. Others can be adjusted based on the conditions like night, daytime, and rain. These features enable you to switch to the right mode without removing your hands from the handlebars.

How bright should my rear bike light be?

Rear bike lights are sold by lumens, and the lumens are equal to how many candles worth of light one can shine. Rear lights usually output somewhere between 300 and 800 lumens, though the ones that provide 800 lumens aren’t necessary for any road cyclist. This is because they are very bright, and the light they emit is scattered, making them less useful on the road.

Road cyclists should have a light that outputs between 300 and 400 lumens. It will light up the road almost as well as a cheap 800 lumen light would, while not blinding oncoming traffic and letting you have a better view of the road.

What is the most powerful bike light?

The Niterider Lumina Byte is our pick for the best cycling light. It has an impressive and bright 1100-lumen output that works well in daytime and nighttime. The light itself consists of 5 Light Levels plus 7 Daylight Flash Modes. It is one of the most powerful bike lights on the market.
Its battery life is 10 hours.

The Lumina Byte is made of durable materials, including reinforced nylon. It has a waterproof rating of IP68, which makes it a suitable choice for wet conditions. It also is designed to withstand crashes. We recommend using the light as a headlight even if you purchase it specifically for its tail-light abilities. We discourage using the Lumina as a tail light because of its powerful light output and its rechargeable battery.

Conclusion

So what makes a great light? How do you decide which is the best bike light for your situation? You may have a bike that stays in the garage most of the time, so a rechargeable lighting system is a perfect fit. Not only will it save you money, because you can plug it in at night for a full recharge, but you can take it with you while you travel. If you want a bike that you ride year-round, rain or shine, you’ll want a light with a high-quality, durable design to handle all weather conditions.
