NiteRider Sentinel tail light review

It has been a little over eight years since we wrote our non-scientific rear light comparo. Planet Bike’s Super Flash rear light was a top favorite and it is still one of my personal favorites.


We were offered to review the NiteRider Sentinel rear light featuring lasers. Yup, lasers! In top of the lasers, this light also features a 2 Watt LED light producing about 40 lumens. Let me tell you, even without the lasers, this light is freaking bright. Another cool feature is that the Sentinel is a USB rechargeable light-a huge plus in my book.


I’m guilty of purchasing those inexpensive Chinese laser rear lights and they eat batteries like crazy, not to mention that the quality of the lights was horrible. Lesson learned.


We used the NiteRider Sentinel during most of our weekly nightly off-road cycling ride. Our local ride offers a variation of horse trails, small streets and big avenues; a rear light is a must for safety reasons. The Sentinel performed with no hiccups even going through some bumpy trails.


The Sentinel was also tested during our morning rides to the beach on Pacific Coast Highway. Although the lasers were ineffective during daylight, the 2 watt LED was clearly noticeable.


USB rechargeable
Super bright 2 Watt LED light
Freaking Lasers!
Mount can adapt to most seatpost shapes and sizes
NiteRider Quality
Good run time
5 running modes

Lasers are invisible during daylight
A little pricey at $50.00

What I would change:
I think that the concept of having virtual laser bike lanes is a good one, however, I don’t really think that we need a laser on the right side since most of us ride close to the curb. It would also be a good idea if the left laser would be 3-feet away from the bike since a few states have a mandatory 3-feet passing law.


With its super bright 2 Watt LED, convenient mounting strapping system, USB charging and cool lasers; I can definitely see the NiteRider’s Sentinel being one of my favorite tail lights.
