Florida requires you to have a white light in the front and a red light and red reflector in the rear. If you put a red light on the front you will be in violation of Florida Traffic law and if you put a white light on the rear you will also be in violation of Florida traffic law.

I don't know if it can be stated any more plainly that that.

I suggest a good front headlight that is bright and has different settings and two good red tail lights that have multiple settings one placed on the seat post and one placed on the left seat stay about half way down the seat stay tube.

The only thing a white light to the rear is going to do is blind traffic coming up from behind. Florida traffic law is very clear on the lighting requirements so if you do your own thing don't complain when you get cited for failing to obey the law on lighting.
