Light Up The Night: While it is certainly very important to see where you are going when riding a bicycle at night, it’s even more vital to make sure other people, particularly motorists, can see you. Many bikes come with reflectors on the pedals and the wheels, and often the front and rear as well. But reflectors only work when car headlights reflect directly off of them (that’s why they are called reflectors), so on a dark street a bike with only reflectors is pretty much invisible. To make yourself more visible in all light conditions, it’s a good idea (and the law in Massachusetts) to add a white headlight to your bike, and a rear red light is far better than the tiny reflectors on most bikes. It doesn’t matter whether the lights blink or not, so get whatever style you like. If you don’t have pedal reflectors, the law also requires reflective ankle straps. And the law also requires that you be visible from the side, so if you don’t have wheel reflectors, wear a reflective vest or jacket, stick some reflectors on your messenger bag or pack, wrap yourself in holiday lights, or whatever else makes you visible.
Sound like a lot of stuff? Go minimalist with front and rear lights and something reflective (or least light-colored) on you. Just avoid the bike-ninja-dark-clothing-no-lights look!
