    REI Members get back an estimated $ 4.50 on this item as part of their annual member refund.

    The REI Member Dividend

    The REI dividend is a unique benefit of membership in the REI co-op. It's comprised of your member refund—typically 10% back on eligible purchases—and/or your REI Visa® card rebates.

    Each March, active REI members and REI Visa cardholders who earned a rebate receive a refund in the form of an annual dividend notice.

    Only active members receive annual dividend notices. To maintain your active status as an REI member, you need to make net merchandise or shipping purchases of at least $10 per year, unless you joined that year. Member numbers are issued in one name and only that person receives the member refund. Your number can be used by others in your family, but it cannot be transferred to someone else.

    Knog Blinder 4 Front Bike Lightis rated3.75out of5by4.
    Rated2out of5byfromNot the BestWill have to return it as the Serfas Thunderbolt is a superior light. The short battery life and the unnecessarily complicated charge and store instructions are a major shortcoming. I used the Thunderbolt today and it is vastly superior.

    Rated4out of5byfromSmall, effective and unobtrusiveOther than the fact that it works reliably and is easy to recharge, the greatest virtue of this light is that it is inconspicuous. It is small and looks a lot more like a reflector than a light. That makes it much less likely to be stolen than lights that are more obviously, well, lights. The light that it throws is adequate rather than spectacular -- but it does the job. The built in USB charger works easily and well. The clasp is a bit eccentric (a good thing in foiling thieves) but easy and solid. The only real negative is that the switch is rather annoying: there are lots of flashing modes and getting the light to simply turn on all its LEDs is rather hit or miss.

    Rated5out of5byfromGreat Helmet Light!What a great product! I was looking for a long time for a Very Light Weight Helmet light that I can attach and detach easily and the Knog Circle White is perfect. See my photos for the Helmet attachment. It looks professional on my Specialized Prevail Helmet and attaches securely as if it was made for the Helmet. It's so light-weight that you barely feel it's there. I use it for night riding and it is very noticeable and provides that extra edge of safety. When you turn your head toward cars they notice it!

    Rated4out of5byfromGreat visibility lightThis is a great, extremely compact light. It throws out a lot of light, but in a very wide beam. This makes it ideal for keeping you visible to other vehicles. It's probably good enough to use as your only light, but I really like it as second light that makes me more visible, while a primary headlight with a more focused beam lets me see where I'm going. With it's low weight and flat shape, this would be the perfect helmet-mounted light, but its mounting is designed only for handlebars. I actually strapped a short piece of plastic plumbing tube to the front of my helmet so I can attach the light. Even with this extra hardware, the weight of the light on my helmet is negligible. The charge seems to last as long as advertised. USB charging is very convenient. The light has a small tab under the mount that flips out, so that you insert the light into a USB port like a memory stick. A small tiny led on the switch glows red while it's charging, turning green when it is fully-charged. It's nice that you don't have to use a separate cable, but the unit is a little bulky. I have to put a book under my laptop to raise it enough to allow light to plug into the USB port on the side. With the light plugged into the back of my desktop computer, I have to bend over to make sure the charging light is on. The battery is not replaceable. However, it will probably last a long time, and REI's return policy will come to the rescue if you feel the battery degrades too quickly. My only other complaint is that the flashing modes make me a bit queasy. This happens to me with almost every flashing headlight, except for the Dinotte, which puts a pause in between sets of quick flashes. I've focused on the shortcomings of this light, but I should stress that I think it's a fantastic light.
