NiteRider Sentinel 40


Create your own cycle lane with the NiteRider Sentinel 40 Rear Light. Twin lasers project lines on the ground to help passing traffic maintain a safe distance.

The Sentinel 40 Tail Light has a powerful 2 watt LED, has 5 modes (steady and flashing), is USB rechargeable and has a brand new safety feature, Laser Lanes!

NiteRider strive to push the boundaries of lighting technology in order to deliver the most advanced, best performing bicycle lights available anywhere in the world. These lights are built in California.


The all-new Sentinel 40 Tail Light is NiteRider's newest model in the Sentinel series.

With five (5) light levels and a powerful 2 watt LED projecting 40 ultra-bright lumens, it's a lightweight portable package that raises the bar for self-contained LED tail lights. But this isn't a normal bicycle tail light; the Sentinel 40 sets a new standard in safety with Laser Lanes! Turn on Laser Lane mode and it projects ultra-bright laser lines onto the ground, giving the cyclist their own virtual bike lane.

This unique safety feature sets the Sentinel 40 apart from other "be seen" tail lights on the market.

And it's USB rechargeable with up to 18-hours of run time on a single charge. Protecting cyclists, the NiteRider Sentinel 40 Tail Light with Laser Lanes makes every ride safer when the sun goes down.
