The NiteRider Sentinel 150 USB Tail Light is always standing guard with its ultra-bright laser emitters that project a virtual bike lane around you so traffic knows just where you are and how much space they need to give you. In addition to the lasers, this USB-rechargeable light can simultaneously shine a 150 lumen rear blinky that's sure to grab the attention of upcoming vehicles, and a special Group Ride Mode lowers its output so riders behind you aren't blinded when you're out with the pack.

Simply the best rear blinky-- after trying many. Reliable and easy to charge. Never leave home without it.

I use the rear blinky EVERY ride. It is highly visible and easy to charge. Very good product.

I like the brightness of the light, which alerts cars of my presence on the road.

A high-visibility, long raqnge flasher
by Lsbar

I've used two of these tail lights. They are so visible and attract so much attention that I've had cars slow down near me just to see the source of the flashes.

The future so bright!

I am thrilled with how bright this light is. LED technology has come so far and become so inexpensive. I can remember when 150 lumens was really bright for a HEADLIGHT! The lane markers are great, too. Run-time is ample for my 5 mi. commute. Seems to recharge very quickly.

The combination of the strong rear light and the laser lines on the road provides greater confidence that I have the attention of cars in heavy traffic.

Awesome Light!

This is an awesome light but a horrible mount! If you can clip it to your seat bag, it will never come off, however using the seat post mount... well, any bump will shake it loose. Really an awesome light, it's bright and lasts for hours on a charge. The seat post mount is just terrible! I used this for about 4 rides and lost it when using the seat post mount. It's bright as heck and really a great light but will easily fall off when you hit a bump. I may buy another as long as I don't use the included seat post mount. Did I mentions it has a terrible mount?

Seriously effective lighting system!

NiteRider is a superior rear-facing light. Visibility is excellent! Multiple lighting modes enables rider to vary the light emitting frequency and intensity. Use the light in low-light levels or during bright daylight for optimum safety.

During low-light conditions the lane marking component is a valuable feature that guides vehicle drivers to preserve the bike lane distance and also adds to the overall visibility.

Assembly is rugged and is easily recharged in relatively short charging time.
