Do I really need lights on my bicycle?

So one day after work you purchased a commuter bicycle from the local bike shop and decided to take it for a spin around the neighborhood just as the sun is going down. Or you’ve got a top of the line road bike and decided to take off the reflectors to lighten the bike, figuring the rechargeable USB lights on either end of the bike are all you need. In either instance, you’d be breaking the law in Florida.
