If you have to ride your bike at night, there's no such thing as wearing too much reflective material — after all, you want to make yourself as visible as possible to those with whom you share the road. But a flashing light can ensure a driver spots you well before the headlights of their car do, and with a pair of these glowing LightSpurs clamped to the back of your shoes, you'll stand out like a sore — but safe — thumb.
Powered by a small CR2032 watch battery, the waterproof LightSpurs will run for about 100 hours in flashing mode before you need to swap in a new one. They can also be set to steadily glow, though that will reduce your battery life. They sell for about $20 each, but in theory, you only need to wear one on the side of your bike that's most visible to traffic. Unless you're going for the whole wild west effect — in that case, a pair of spurs is definitely the way to go. [Nathan Sports via Gizmag]
