NiteRider Sentinel 250 Cycle Light
NR-5089
The NiteRider® Sentinel™ 250 is designed to increase cycling safety by way of 2 varying flash patterns and 2 steady beams (High/Group Ride Mode). Behind the durable red lens and casing are two powerful LEDs that emit 250 lumens in the brightest Daylight Visible Flash setting, allowing you to be seen day or night. For enhanced safety, the Laser Lane modes (3) are designed to project ultra-bright laser lines on the ground. This creates a virtual lane for the rider, further increasing visibility.
It Also features an innovative Group Ride Mode where you can be seen without distracting fellow cyclists’ attention from the pavement or dirt. At 116 grams the USB rechargeable Sentinel meets all required FL1 Standards for impact testing and dust/water resistance. The easy on-and-off seat post strap with quick release tab makes the Sentinel convenient when you do need to give it a quick charge.
The Sentinel™ 250 complies with FDA standard for lasers, notice No. 50, 2007

I received a damaged product which I returned back on Aug 25th 2021. But after that there is no communication from Cyclop - it's been more than a week. I have written 3 emails about the product being picked up by their courier. Till date I have neither received the replacement product not the money.
Hi Darshan, Sorry about the delay in response. we noticed faulty light has been picked. Our team will get back to you on priority tomorrow to sort this out.

Been using this light for about 3 months. The high power flash modes are easily bright enough to be clearly visible even during the day. Battery life is decent; as I switch between different modes based on need, I get about 5-6 hours out of a single charge (so for my use, I charge it on a weekly basis). The lasers are very bright as well, but haven't really given them a good run at night to see how it affects vehicles behind me, especially the impatient 2 wheelers. The low power indicator helps you charge before it runs out. I love the sleek looks, and how robust this little unit feels. The strap makes it easy to move between bikes if needed - no worries about the light jumping out of the clip or the strap coming loose. Well worth the price - would buy again!

This light can be seen from over a kilometer and super bright. I feel safe on highway rides not to be rear ended. and in close proximity traffic the laser lane lights do wonder. The cars maintain their distance, and I get to keep my own lane :) . very happy with my purchase. thanks Cyclop!
