There are three 12 volt lights total, two 55W halogen sealed beam lights for the front and one for the rear. The bulbs are replaceable and are mounted in a glass reflector that has a steel backing plate. These flood lights mount on the top or bottom of just about any roof and can be adjusted a few degrees either up or down. They will fit on other brands of roofs provided the mounting surface is correct. The floodlight mounting hardware is supplied and the lights have wire pigtails but you must supply the wire and switch to the power source.
(switch and wiring are not included)
Specifically made for use with FTD brand roof but may fit others. Call if you have any questions.
