Specification / Details


It is designed to increase cycling safety by using 2 varying flash patterns and 2 steady beams (High/Group Ride Mode). There are two Laser beams that project two lines onto the road, clearly marking “Your Space”. I use that and am amazed at the driver response.

 There are two powerful LEDs that emit 250 lumens in the brightest Daylight Visible Flash setting, allowing you to be seen day or night. The Sentinel™ 250 complies with FDA standard for lasers, notice No. 50, 2007

• Daylight Visible Flash (DVF)
• Highly visible laser lanes
• All in one, Laser and tail light!
• Convenient USB rechargeable
• Group Ride Mode – be seen without distracting fellow cyclists
• Easy on and off seat post strap mount with quick release tab
