The CatEye Rapid 5 tail safety light includes the high power center SMD-LED and two 5mm LEDs of the Rapid 3, but adds two more side mounted high-power SMD-LEDs for maximum visibility from all directions.
Four modes allow you to customize your visibility. The rapid mode is an all out attention grabber, using all 5 LEDs in a unique pattern guaranteed to get you noticed. The peleton-friendly pulse mode foregoes the high-power center LED to save blinding your riding buddies, while the constant and flashing modes add daytime safety options.
2 included AAA batteries will run the Rapid 5 for up to 100hrs and comes with the SP-11 FlexTight bracket.
