The Best Pair of Lights for Any Ride, Day or Night

The Trek Commuter Pro RT and Flare RT Set is a complete front and rear lighting solution designed for riders who want the highest level of daytime and night visibility in a single matched package. The set pairs the Commuter Pro RT front light - featuring Kindbeam technology and a maximum 1000 lumen output - with the Flare RT rear light for daytime running light visibility from up to 2km away. Together they cover every lighting situation from early morning commutes in full darkness to midday riding where daytime running light visibility is the primary safety requirement.

The set is designed around the principle that the best lights are the ones that stay on every ride rather than being reserved for specific conditions. Both the front and rear lights in this set are capable of performing as daytime running lights and as night riding lights, removing the need to carry or swap different lights for different times of day.

• Our best pair of lights. Daytime running lights for visibility, and Kindbeam that lights the way while staying out of oncoming riders' eyes.
• See and be-seen light set for everything you need to ride with lights every ride, day or night
• Commuter Pro RT with Kindbeam keeps light on the ground ahead of you and out of oncoming riders' eyes
• Flare RT provides ultimate visibility for any road, city, or path
• Specifically designed focus, flash, and range flash patterns for daytime visibility for up to 2km
• Commuter Pro modes: high 1000LM — 1.5hrs, low 500LM — 3hrs, day flash 300 LM — 12hrs
• Flare RT Flash modes: 90LM — 6hrs, 45LM — 12hrs, 5LM — 15hrs, Steady modes: 25LM — 4.5hrs, 5LM — 13.5hrs

Commuter Pro RT with Kindbeam - 1000 Lumens Without Blinding Oncoming Riders

The Commuter Pro RT front light introduces Kindbeam - Trek's proprietary beam shaping technology that directs more light onto the path ahead of the rider while reducing the spill of light upward toward oncoming riders' eyes. Standard high-output front lights illuminate the path effectively but also direct significant light horizontally and upward, which blinds oncoming cyclists and pedestrians on shared paths and creates a visual hazard at the exact moment visibility matters most. Kindbeam addresses this by concentrating light where it is needed and redirecting it away from where it causes problems.

At 1000 lumens on high, the Commuter Pro RT provides sufficient output for unlit roads and paths at commuting speeds. Three modes cover the full range of riding conditions:

High - 1000 lumen, 1.5 hours runtime
Low - 500 lumen, 3 hours runtime
Day Flash - 300 lumen, 12 hours runtime for daytime visibility

A visible fuel gauge on the light displays remaining battery without requiring the rider to check an app or estimate remaining charge. A wireless connection links the Commuter Pro RT to the Flare RT rear light, allowing both lights to be controlled from the front unit. The charge-back feature allows the Commuter Pro RT's battery to be used as a power bank to charge other devices - a practical feature for commuters who use the same USB source to charge both the light and their phone or cycling computer.

Flare RT - Ultimate Daytime and Night Rear Visibility

The Flare RT rear light completes the set with daytime running light visibility from up to 2km away and five output modes covering flash and steady configurations for day and night use:

Flash modes - 90 lumen for 6 hours, 45 lumen for 12 hours, 5 lumen for 15 hours
Steady modes - 25 lumen for 4.5 hours, 5 lumen for 13.5 hours

The specifically designed focus, flash, and range flash patterns of the Flare RT are engineered for daytime conspicuity - the light is designed to be seen in bright ambient light conditions rather than simply being a nighttime flasher running at reduced output. The wireless connection to the Commuter Pro RT front light allows the set to be operated as a coordinated system from the front unit, simplifying light management during a ride.

FAQs

What is Kindbeam technology on the Commuter Pro RT?

Kindbeam is Trek's proprietary beam shaping technology that directs more light onto the path ahead of the rider while reducing upward light spill toward oncoming riders' eyes. It allows the Commuter Pro RT to run at 1000 lumens without blinding cyclists and pedestrians on shared paths - providing maximum visibility to the rider while avoiding creating a hazard for others.

What does the charge-back feature on the Commuter Pro RT do?

The charge-back feature allows the Commuter Pro RT's internal battery to be used as a power bank to charge other USB devices - phones, cycling computers, or other accessories. For commuters who carry a phone or device that needs topping up during a ride, the front light doubles as a portable charging source without requiring a separate battery pack.

How does the wireless connection between the front and rear lights work?

The Commuter Pro RT front light connects wirelessly to the Flare RT rear light, allowing both lights to be controlled from the front unit during a ride. This means the rider can manage the full lighting system without reaching back to the rear light to change modes or check status.

What are the runtime options across all modes for this set?

The Commuter Pro RT offers 1.5 hours at 1000 lumen, 3 hours at 500 lumen, and 12 hours in 300 lumen day flash mode. The Flare RT offers 6 hours at 90 lumen flash, 12 hours at 45 lumen flash, 15 hours at 5 lumen flash, 4.5 hours at 25 lumen steady, and 13.5 hours at 5 lumen steady - covering everything from maximum output night riding to extended low-output daytime commuting.

Is this set suitable for unlit rural roads as well as urban commuting?

Yes. The Commuter Pro RT at 1000 lumens on high provides sufficient output for unlit roads at commuting speeds, while Kindbeam technology keeps the beam focused on the path rather than blinding oncoming traffic. The Flare RT provides rear visibility from up to 2km during the day and multiple flash and steady modes for night riding - making the set appropriate for both urban and rural riding conditions.
