Rated 4 out of 5 by from Two-in-one extra visibility This clever little device has a red LED-driven light rope behind a reflective strip. When headlights shine on the band the reflective part does its job, but the LEDs provide some visibility even unilluminated. I use a pair as arm bands so I can make visible hand signals at night; unfortunately they're a bit large for this purpose, so I have to wear them at my elbow instead of around the wrist. Battery is a standard CR-2032 watch battery and pretty easy to replace, although you do need a small screwdriver. The flash/steady/off switch is a simple pushbutton and easy to accidentally turn on in your bag.

Rated 4 out of 5 by from Great Cycling Safety Gear Been using this for all night-time cycling rides especially on busy roads with little to no available lights. Highly reflective material coupled with dual illumination mode, and when worn on the ankles gives an attention-grabbing up and down motion (when viewed from behind). This definitely increases the wearer's visibility from nearby traffic. The minor strike against this is the long strap end that's flapping if this is worn as an ankle band, but that can be fixed with a rubber band. Simple yet highly effective product. Recommended product especially for low-light riding.

Rated 2 out of 5 by from strap slips I bought this for running, and as someone else has noted, it doesn't stay in place on my upper arm. I have small arms, but it does fit. But the elastic doesn't stay in place in the adjustable connector, and it keeps sliding down my arm. Perhaps for cycling, or as a dog collar, it would be fine. I've had to just take it off and carry it. I may try to find some other use for it, but am strongly considering returning it.

Rated 5 out of 5 by from Going on 2 years as a second dog collar I love this light. I bought it a few years ago not knowing what to expect. I figured I could use it commuting by bike or for my dog. It turned out perfect for my 50 lb poodle. They do sell an extension which you can use for a larger dog. She's dark brown, I put this on when we walk the neighborhood at night. She gets lots of comments and is a bit more visible. It's also nice to have this on when she's out in the yard at night. I can see her zooming around. I've only had the change the battery once (the battery costs more then the product!)

Rated 5 out of 5 by from I love these I love these lights. I use them as a strap to keep pants out of my chain. On my left arm to help signal turns in the dark. I use 2 strapped together around my dog's neck when I run her. The light strip can be removed from the strap so you can rinse them off. All around a great product. The only bad thing I have to say is that I seem to lose them, but that's not their fault.

Rated 5 out of 5 by from Great. Very Bright. I bought one of these for myself and another for my mom as a gift. We both love it. The light is bright red and can be adjusted with a quick push of a button to be either a stream of light or flashing. I'm thinking about getting another one so I have one on my arm and leg just to bring more attention to myself when it's dark outside. The packaging shows that it could also be used attached to a dog collar but you'd have to have a small-ish dog because the strap isn't all that big to go around their neck if you have a larger pet. That is a bit disappointing because I do have a dog that is too big for it but it's not a deal breaker for the product. I also wear it when it's dark and I'm out running with my dog. I feel comfortable wearing it and confident that I will be seen because of the light it emits and its reflectivity.

Rated 4 out of 5 by from safer walking/running at dusk I have a small the tightest adjustment works for me. unsure how it would work in biking, but it helps a lot with dusk and dark running or walking....the cars notice I'm there and the last minute swerves to miss me are appreciated, I suspect, by the drivers as well as myself. This is a big improvement over wearing a white shirt to be is clear the drivers are aware of me much sooner with this device. A very worthwhile safety investment by me!

Rated 4 out of 5 by from Makes a great belt! I added a piece of elastic to the band to make this an adjustable waistband. I use it to cinch in my rain/cold weather jackets for early morning (dark) winter commutes. It puts something flashy and reflective up higher-closer to sleepy drivers eye level than my rear taillight, and also blocks drafts effectively.

Is the battery replacable, and if so what type?

How long is the strap? I want to use it just below my knee; need it to be at least 12" (plus whatever is needed to fasten it)

Asked by: lenelson
The BRT strap measures 8 inches at its smallest setting. The strap is very adjustable and should meet your needs. The strap attaches via a side-release buckle.
