Never be missed. 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. Lighting mode memory function, compatible with RM 1 saddle rail bracket, rear rack mount and clothing clip optional. 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. Compatible with the all new RM 1 Saddle Rail bracket and the clothing clip, available separately.
