For the roof warn makes some 2" atv/utv lights that are well built and far superior to the ones John Deere offers which in my opinion are garbage.
I have 4 of the HID ones on the roof (https://www.warn.com/atv/lights/W200X...ot_Beams.shtml) and the light output is amazing daylight to at least 400'. They also offer 2" Spot (Link) and 2" Fog (Link)
In the grill I replaced the John Deere lights with Warn 4" HID's as well (Link)
As you can imagine their is no lack of light. You also lose about ten pounds of wire switching from the crazy John Deere Harness, which does not do well with water at all, the warn harnesses are much cleaner and better quility connections.
