I'd also add an LED third brake light to the engine grill. Compared to emergency flashers, it is a simple 2 wire connection. You can also add a motorcycle brake flasher at same time. It flashes the 3rd brake light 6 quick time then 3 and then steady on. It is an attention getter. (It may not be legal in all states - FL does not have safety inspections at all).
