Flare RT Rear Light
Bontrager Flare RT Rear Light Review
Tested and reviewed for bikepacking use
The Flare RT produces 90 lumens in a focused beam pattern visible from up to 2km in daylight. The daytime running mode uses a distinctive flash pattern that grabs driver attention without blinding following riders. USB-C rechargeable with up to 12 hours of runtime.
Who Is the Bontrager Flare RT Rear Light Best For?
Road and gravel riders who share lanes with traffic and need maximum daytime visibility. If that describes your riding style, the Flare RT Rear Light should be at the top of your shortlist. It sits in the Lighting category alongside 11other products we've reviewed.
How It Compares
At 60g and $55, the Flare RT Rear Light is 32g heavier than the lightest option in this category (the Nitecore NU25 UL Headlamp at 28g). The most budget-friendly option is the Goal Zero Crush Light Solar Lantern at $20.
The price-to-weight ratio comes in at $92 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.
