I don't know if light bars or auxilliary lighting would be illegal in Florida. But it's not likely that law enforcement would bother enforcing it if it was illegal. Unless the owner of said lighting was purposely lighting it up in other driver's faces.
Chumbo - Maybe you can be our lighting pioneer. I'm in agreement with Mark in as much as I don't think switching your headlights / bulbs is going to make much or any difference for what you need / want. Ultimately a light bar up over the roof with a gazillion lights on it would be best. But I dislike the idea of something sticking up in the air, up over the roof. Wind drag and wind noise would be a problem (for me). And mounting them too low would also be detrimental.
I do like the look some of the rally cars have where they mount big lights above the grill, higher than the headlights. But again, wind drag.
I also tippy-toe drive when I'm in a few select areas around my house where the deer congregate. There are areas here where they feel welcome, right beside the road, and graze. I've never seen one hit killed though. They also must be good parents and teach their little ones about road and traffic safety. Although, about 10 years ago, one about ran into my driver's door. I frequently ride with my left 2 windows down, he was so close I could hear his hoofs clicking on the asphalt.
