|Knuckle Lights, running lights you wear on your hand|
The FactsKnuckle Lights are one of those products that you see the small ads for in the back of magazines like Runner's World and wonder about it. Either it's junk or it's a hidden gem. When I saw that one of the runners I really respect post a photo of herself using them on instagram I decided to give them a go. At the time, I was running at night a lot and needed a way to light my path that was not a headlamp. (I don't have anything against headlamps, I've never tried one but it seems like wearing something extra on my head would annoy me. If you have a great headlamp you think I should try let me know.)
A dislike for headlamps, yet a need for light on his morning runs is was lead founder Dan Hopkins to create Knuckle Lights. Knuckle Lights are wide-beam, 45 lumen lights that are worn on your hands. An adjustable silicone strap holds the lights around you fingers between the first and second knuckles. They come in sets of two, one for each hand, and are powered by 2AAA batteries each (included). The back of the light, where it sits against your fingers, is lightly padded to make it more comfortable. Each unit has 3 modes: high (45 lumens), low, and blinking. Knuckle Lights are weatherproof, come in 5 colors (the plastic of the unit, not the light itself). The current price is $39.99 and they are backed by a 5-year warranty.

The backside of the unit, where it sits against your fingers is also the battery cover and has a dense foam like material over it for comfort. This also seems to keep it from slipping around much once your hand starts to sweat. I wear mine on my left hand, which means my wedding ring pushes into it a bit (see photo at right) and if my ring is on straight it can be a little uncomfortable, but with my ring turned to the side or turned to my palm, it's no problem. This is really more of a user problem than a design problem, I could just take my rings off.
I've had my Knuckle Lights for 8 months and have ran with them in heat, cold, and light rain with no issues. I did think that they were having a problem with the cold for a while, but I replaced the batteries and they were fine. The batteries that come with the units do not seem to last long, once switching to name brand batteries, I got more life out of them. I'm also glad that the batteries are easy to change, no screwdriver needed.
ConclusionI like them, and for someone like me who doesn't like stuff on them when running, that's really saying something. I won't say they disappear when I run, I do know they're there the whole time, but they're pretty comfortable. While they can be a little hard to adjust, once you get it right, you shouldn't need to adjust them. Compared to holding a flashlight, it's no contest, the Knuckle Lights are far superior to that. The high setting of 45 lumens is comparable to your mid range headlamps and so is the price tag, but with Knuckle Lights you're getting two lights. The two lights is something I wish were different though, especially knowing now that I only like to use one at a time. I was hesitant to spend $40 for a pair, but I could see myself being much more ready to spend $20 for one.
Although Knuckle Lights were the first of their kind, they do have a competitor now in the Nathan Zephyr Fire Hand Torch. I have not tested the Nathan lights, but just from looking at the specs, photos, and price (MSRP $45 for one light) I would choose Knuckle Lights over them, and not just because of the price. The Nathan light is still a flashlight you hold, it's just also strapped to your hand.
While I do like my Knuckle Lights one issue I've had is that batteries don't last long, but I am using them for 45 minutes to over an hour at a time. Next time I replace the batteries, I'm going to try to keep track of how many hours I get out of them and will update this post with that information. Another thing that's worth mentioning, not for the issue itself, but for the great customer service experience I had: one strap snapped the second time I used the Knuckle Lights and they were quick to respond to my email, and replaced the whole unit at no cost to me.
For someone who runs in the dark or low-light conditions and doesn't want to wear a headlamp, Knuckle Lights are a great option.
