I just receieved a pair of Zackees turn signal gloves in the mail and they're a quite ingenious and intuitive way to improve your turn signalling. I don't know if they'll save your life or improve bike-car interactions, but I do know they're a big hit with the under-6 crowd. My kids think they're pretty much the coolest thing ever and keep asking me to make the lights come on when I take them home, so that's something.
I've seen a lot of turn-signal type devices for cyclists, but have passed on them as they seemed too hard to deal with. But Zackees are pretty easy to use without changing the way you ride. On the inside of the index finger and on the inside of the thumb are two metal rivets. When these make contact, the arrow lights up on the top of your hand. So if you're signalling as you normally would, you just have to make a point to bring your thumb down and voila - car-style turn signal.
The gloves are high quality and the lights are very bright. It's all powered by small, rechargeable batteries, recharging device included. I got gloves that are a little smaller than I like, which might be user error on my part, or maybe they run a little snug. But be warned.
Created by a Google Engineer, these Turn Signal Gloves are one of the best ways to increase your visibility and communicate your turning intentions to other vehicles on the road.
Zackees™ Turn Signal Gloves™ features an ambient lights sensor which boosts visibility during the day and extends battery life at night.
The Ultrabright Rechargeable Pack delivers more power per blink than disposable batteries. This upgrade includes four rechargeable coincells and a charger pack. We are calling this combo the Ultrabright Rechargeable because the gloves are significantly brighter with these rechargeable coincells.
I haven't had to rechage mine yet, but it seems pretty intutive, and changing the batteries out is pretty simple - even if it is a little bit of a hassel to have another thing to maintain.
At $60-$70, they're more expensive than your aveage glove, but with more utility.The gloves are the kind of thing I would never buy for myself, because I'm a cheapskate; but I would really enjoy them as a gift.
