Over the past twelve or thirteen years I’ve purchased at least a two dozen taillights—some were brighter than others, but the new Niterider Sentinel 40 Taillight is in a class all by itself. I am not one to gush over new cycling gadgets, but this taillight is the coolest product I’ve ever put on my bike! The folks at Niterider sent me one for review and now I am going to give this awesome light away to some lucky reader (see the details at the end of this article).
The Sentinel 40 has a super bright 40 lumen output (and thanks to a well-designed lens it actually looks much brighter than that). The taillight has four modes (two flashing, plus high and low steady). I never use the steady (always on) mode because a flashing light is so much easier for cars to see (plus it saves battery life). In the fastest flash mode the built-in 1000mA LiPo (lithium polymer) battery on this unit will last an amazing seven and a half hours. The charge time for this light is only four hours and uses a USB cable which is included with the light. As for size, the light is approximately 3.5 inches tall, 1.5 inches wide and 1.5 inches deep. For the “weight weenies” among us, it weighs a mere 2.5 ounces (73g).
I’ve saved the coolest feature for last: the Sentinel 40 has Laser Lanes which project two parallel bright red lines onto the pavement to give you your own personal bike lane. I honestly don’t know how far back cars can see this feature at highway speeds, but in town it a obviously helps. One warning: you are going to have to be ready at every stoplight to tell motorists about the lights since it seems like everyone is curious about them. Did I mention how cool these Laser Lanes look? By the way, the Laser Lane lights are real lasers, so don’t look directly into them.
Like most bicycle taillights, this unit can be mounted to either the back of most saddlebags or attached to your seatpost with the included clamp. While the clamp seems more robust (sturdy) than most clamps, I prefer to mount mine on the saddlebag so the light will sit up higher on the bike. I used to lose a couple of taillights every year because they would fly off my bike the first time I hit a big bump on the road (but I wouldn’t notice it until I got home). The simple solution is to mount your taillight on the saddlebag as usual, then wrap a zip tie (cable tie) around your light so it extends behind the clamp (I haven’t lost one since I’ve started doing this).
The Niterider Sentinel 40 Taillight retails for $49.99 and is available at your local bike shop or online for a couple dollars less (but be nice and buy this from your local bike shop).
I never keep the products that are sent to me for review, but I am going to really hate giving up this taillight! To enter the contest for the Niterider Sentinel 40 Taillight all you have to do is pick a number between 1,000 and 1,500 and enter it in the comment section below (you don’t actually have to make a comment). The contest ends at midnight (CST) on Monday, December 28, 2015. After the contest closes I will use a random number generator to pick the winning number. If no one guesses the exact number the person with the number closest to, but not over, the winning number will get this slightly used taillight. In case two or more people chose the same number the first person to pick the number will be the winner. This contest is for U.S. residents only and only one entry per household allowed. When the contest is over I will publish the results in the comments section of this article. I will send this product to the winner via U.S. Mail.
