How to use your rear bike lights?
Rear lights are traditionally less bright than their forward-facing counterparts, which lend themselves to having a flash feature for better visibility at night. However, to ensure proper distance determination for your fellow road warriors, a steady constant light should be maintained during riding. Having a longer flash speed is a good comprise for most riders who do not want to have two rear lights on their bicycle. One good option for your rear bike light would be THIS REAR BICYCLE LIGHT. The mode selection option helps you switch between the continuously on mode to the different flash setting. However, regardless of what light you choose to install on your bike the main thing is to have a rear light!
