Knowledge base

The model name is printed on the light and on the original packaging. Most Cygolite lights list the lumen rating after the model name, such as Streak 600.

Our latest products are always shown here on this website, so it is the best place to see what is currently available. We are constantly working on new things, but we are not able to comment or speculate on unreleased products.

Product features and functions vary by model. Refer to the user guide included with your light or the original packaging for details specific to your model.

Product features and functions may vary. Refer to your user manual or product packaging for details.

Cygolite products are designed specifically for use while bicycling. Any other use is not recommended.

Lumens are the common standard for comparing LED brightness. It is the measurement of the total visible light emitted by a source. Most Cygolite lighting systems will have a lumen rating after the model name, such as Streak 600: model Streak, lumens 600.

Most Cygolite headlights compatible with the hard mounts have a helmet mounting option. Visit the Accessories page to find available mounts for your model. We do not have helmet mounts for taillights at this time.

All Cygolite systems are designed to be weather resistant and will work normally in rainy conditions. The systems are not intended for use under water.

It is recommended that you angle the light slightly downwards. Doing so allows you to get the most out of your light in a safe manner.

Charging indicators may vary among products. Refer to your user manual or product packaging for details.

It is recommended that you fully charge your battery whenever possible.

For your safety and consideration, we recommend disconnecting the charger when the device is fully charged and never leaving it unattended.

Different Cygolite models use different chargers that are not interchangeable. Only use the charger that came with the product box. Refer to the battery and charger labels for compatibility.

It is recommended that you only use the included Cygolite charger or cable to recharge a battery. Use of any other chargers may result in damage or personal injury.

Each model and battery type may have different specifications. A battery designed for a particular headlight series may therefore not be compatible with any other series.

Some internal components, such as batteries, are not offered for individual purchase or self-installation. In those cases, the light may need to be sent in for service. Please reach out to support if you need assistance.

Shorter run times may be caused by several factors, including cold temperatures and battery age. In colder environments, warm up the battery by charging it for about 5 minutes before using the product. If your model has an old battery, it may be losing charge capacity and should be replaced as needed.

Give the battery a full charge when you first receive a new lighting system or battery. Try to recharge before the battery runs all the way down, and avoid leaving it fully drained. If the light will be set aside for a while, store it with a partial charge rather than empty or full, keep it somewhere cool and dry, and top it off periodically so it never sits depleted.

Cygolite does not sell products directly and uses a network of authorized dealers and distributors. However, we do have select replacements parts available as a service.

This website is owned and operated by Cygolite, but it does not sell lighting systems directly. Cygolite works through a network of authorized dealers and distributors, so your preferred local bike shop is the best place to buy a light. Select replacement parts are available as a service.

Cygolite products purchased through an authorized reseller are covered by a limited warranty. Please see the warranty page for current coverage details, terms, and how to start a claim.

We are unable to accept returns or issue refunds for products that were not purchased directly through us. Many online listings look official but are operated by other retailers, so any refund or return request needs to go back to the seller you ordered from. If your light has a defect, we can still help through the warranty process.

Spare parts such as chargers and mounts are available through the Accessories page or at shop.cygolite.com. Please visit your preferred local bike shop for purchasing whole lighting systems.

Cygolite products and their components are manufactured to specific quality standards. Only use original Cygolite parts. Using non-Cygolite parts will void the warranty and may result in product damage or personal injury.

Send us a message through the contact form and our team will follow up by email. Service hours are Monday through Friday, 8 am to 3:30 pm US Pacific Time, excluding US holidays.

Contact us first through the contact form and describe the issue. If service is needed, our team will provide return instructions along with your case reference so your history stays in one place.

We do work with a group of review and testing partners. Because of the volume of inquiries we receive, we are not accepting new applications at this time.

Our sponsorship commitments are planned well in advance and our roster is currently full, so we are not reviewing new sponsorship requests. If that changes, we will announce it here rather than by individual reply, so there is no need to follow up or check back each month.

We work with select bicycle parts and accessories distributors in the USA and abroad, and we recommend contacting your preferred distributor for additional information. Our distribution network is established through long-term partnerships, and new accounts are added only on a very selective basis.

We appreciate the interest, but custom branded and co-branded lights are not something we offer. Every light we build carries the Cygolite name, and we keep it that way so quality and support stay consistent for every cyclist.

If you purchased a Cygolite lighting system in the USA and plan on using it abroad, a different charger may be necessary. If you purchased the system in a different country from an authorized reseller, the system should already include the appropriate charger.

Cygolite works with several authorized international distributors that may assist you with product service and support. For more information, contact an authorized distributor in your country or Cygolite Customer Service.

A Cygolite product purchased through an authorized dealer in your country is equipped with components in accordance with local standards and regulations. The Cygolite warranty is not applicable when customers purchase Cygolite products through US resellers that are then used in a different country.
