Loyal guard.

Built with a higher lumen output than most tail lights and a practical, streamlined design, NiteRider's Sentinel 150 Tail Light makes a sound investment in safety for your road rides. Even if you work to avoid getting caught riding in the dark, staying seen during the in-between times, after sunrise and before sunset, is just as crucial.

In addition to a traditional tail light beam, the Sentinel casts two beams alongside you, creating a virtual lane around you for motorists to see. Plus, because a little extra visibility during the day when you're riding in traffic never hurts, NiteRider thought to include a Daytime Flash Mode on the Sentinel 150. An additional six modes help you choose between various levels of output and between a steady or flashing beam, while a low battery indicator will let you know where your battery stands before you're out on the roads. Recharging NiteRider devices is simple and quick with the included USB recharging cable, so if you are running low, recharging won't take all night.

  • Your visibility-enhancing companion for day or night
  • Casts 150-lumen beam plus virtual lane lines onto the road
  • Comes with 7 different flash/steady modes
  • Daytime Visibility Flash helps you stay seen at all times

NiteRider Sentinel 150 Tail Light

  • Familiarity: I've used it once or twice and have initial impressions

The light looked like a great light but from the beginning I questioned the way it attached to the seat post. You have a nice rubber bracket then the light clips into the bracket needless to say my thoughts were correct the light fell off some where during my ride. I have the bracket but no light so that was a 60 dollar ride and I also have no idea when it came off to go look for it.

Just lost mine tonight (which is why I'm on looking for a replacement). It is fine for the road but slight bit of off road and it's gone.
