Frequently Asked Questions
Why is a high-quality bike headlight and tail light essential for cyclists?
A high-quality bike light is critical for both night riding and daytime safety. High-output daytime running flash modes increase cyclist visibility to motorists from up to a mile away, drastically reducing the risk of vehicle collisions.
How many lumens do I need for road, gravel, and commuting?
For urban commuting on lit streets, 300 to 600 lumens is sufficient. For unlit road riding and gravel trails at night, we recommend 1,000 to 2,400 lumens (such as the Ravemen PR2400) to illuminate road hazards and obstacles clearly.
What is Ravemen DualLens anti-glare beam technology?
Ravemen DualLens optical design mimics automotive dipped low-beam headlights. It provides wide, even illumination on the road without blinding oncoming drivers, pedestrians, or fellow cyclists.
How does a Garmin Varia radar tail light work?
Garmin Varia radar (RCT715, eRTL615, RVR315) uses millimeter-wave radar to detect approaching vehicles from behind up to 153 yards away. It displays visual and audible vehicle alerts directly on your Garmin Edge or compatible GPS cycling computer.
