For convenience, sometimes an ultra-compact LED light set serves your purposes for around-the-neighborhood safety or training. Or if you're a commuter, you know the benefit of having multiple lights in case your main beam goes belly up during your ride. Whatever your situation, the Vetta Mercury Headlight/Taillight combo delivers a super bright LED beam and weighs only 31 grams per light. So don't get stuck in the dark where you can't see or be seen...take care of business and stay on your bike.
