If you ride your bike at night, you must have the proper lights for it. A bicycle must have white lights on the front and red lights on the rear. Your bike also needs a red rear reflector and amber pedal reflectors. Turn on these lights any time you're riding between sunset and sunrise. Additional lights on the wheels or body of the bike can make you more visible while adding style and interest to your bike as well. However, these vanity lights may not be sufficient to meet the requirements listed above, so make sure you have these other lights in place as well.
