The Cateye Reflex Auto Rear Cycle Light and Reflector has been designed to exceed the bike light standards in the UK, Germany, USA and Japan. Under UK regulations you should have both a red rear light and a red reflector when riding at night. The Reflex Auto gives you both.

The Reflex Auto will automatically turn on whenever both darkness and motion are detected by the built in motion and light optic sensors. This provides the rider safety both while the light is turned on and while functioning solely as a reflector.

Bike Lights - How Many Lumen Do You Need?

Bike lights are rated in Lumens. A Lumen is the measurement of the total visible light emitted and is commonly used for all kinds of bulbs.

One thing worth noting is that most lights advertise their headline rate. Packaging may say 1000 lumens. Reading the small print they might only do that for an hour. That light may run 500 or 600 lumens for 2 or 3 hours. So it's worth buying a light with more lumens than you need to get decent running times.

There is no fixed agreement on how many Lumens you need for a bike light as it depends on the type of cycling you are doing. As a rough guide we say that:

  • Daytime running lights = 100+ Lumens
  • Urban commuting lights = 50 to 200 Lumens
  • Rural riding lights = 400 to 600 Lumens
  • Trail riding lights = 600+ Lumens
