      Comments about Knog Frog Strobe Front Bike Light:

      I had such high hopes for this. I like how I could easily interchange it from bike to bike and even take it with me on runs. The battery life is the killer. It takes 2 lithium batteries that will run you about $10 for both. I think the thing turns itself on or drains the batteries while turned off, because I need to buy new batteries every few weeks, even when I don't use it. Well, I bought new batteries twice, then I replaced it. If they can figure out a way to ensure battery life, this thing will be great. Perhaps a toggle to engage the battery and the button to turn it on would help prevent accidental turn on or random battery drain. I hope they get back to the drawing board and do some troubleshooting, because the potential is there.

      • Front safety light

      Comments about Knog Frog Strobe Front Bike Light:

      This light is good as a front or rear safety light on overcast / gray days. But, not bright enough for night riding. The claimed battery life of 80 hrs is over stated. My experience is 20-30 hrs on flash mode. I noticed that my light changes modes by it self if riding on rough roads. The rubber strap broke on my light after one month of use.

      Cons

        Best Uses

        • Front headlight

        Comments about Knog Frog Strobe Front Bike Light:

        This is a micro-sized light that runs on 2 tiny button cell batteries (CR 2032). As such, it will not compare to a proper full-sized headlight with a large battery for lighting up your path. This should be thought of merely as a way to improve visibility from the front, and to do that with a negligable amount of weight and bulk. For that purpose, it is excellent.

        It has a wide beam pattern, giving it maximum visibility not only directly in front of the bike, but out to a full 45 degrees to each side, and reasonably good visibility out to about 90 degrees. This is better than the other models I examined in the store.

        Considering its size and power source, it is impressively bright. I can see it lighting up reflective surfaces like stop signs, etc. from a couple hundred feet away or more. It is bright enough to be at least somewhat helpful in daylight. I don't plan to use this to light my path, but in a pinch it could work for that to a limited extent at low speed.

        The light is small, lightweight and unobtrusive when mounted on the handlebar. It stays securely in place. It is trivial to mount and remove without tools and could be switched from bike to bike or to the seat post for rear visibility. It is so small, I see little reason to ever remove it. I found that mounting it upside-down under the handlebar reduced the back-scatter glare. Mounting it that way might make it less weather resistant.

        Combined with a tail light and reflectors, my bike has good visibility now. I don't do much riding in traffic, but it just makes sense to be visible wherever I ride. It is also a legal requirement in most places to have a headlight after sunset. I consider this to be a bit of insurance that does not cost much in terms of weight, money or maintenance.

        Some of the reviewers on another website had trouble with battery drain. I haven't had it long enough yet to notice that problem. Hoping for the best. My rating assumes that I won't have this problem.

          This light is wimpy even when the batteries are good. The ones supplied run down fast and to replace the two watch-style batteries costs more than $10. Don't waste your money.

                This light seemed to drain off the batteries even when shut off. Since the CR2032 batteries are about $5 a piece that was pretty lousy trial and error discovery. I'm going to get something different. On the 2 or 3 occasions when it was not dead, it was about as bright as I expected for being so small.

                I bought both the front and rear versions and both are really nice . They definitely let runners and other cyclist know your there at night. Although I am happy with them I would not recommend it as a primary source to light up the street or a dark trail .
