I just bought a BX25D, and have already found the factory lighting to be brutal. The FEL pretty much blocks all light from the headlights. I want lights mounted high to clear the bucket, wide to clear the sides, and similar to the rear for backhoe work.
Lighting low down to the rear would probably also be good for plowing snow with the 3ph.
White is my preferred colour for most work, but a yellow tint would likely be good while plowing snow while it is still snowing.
As all my work is being done in my own yard, I have no need for flashing amber/strobes.
I liked the idea of the first pic you put up on this thread, with the housing mounted on the top of the ROPS. That would allow the two middle lights to aim forward in a combo spot/flood pattern, with the two outer lights angled down more with flood patterns. A similar pattern could be done to the back, but I think the back would benefit from some adjustability (different requirements for backhoe than for plowing).
I was thinking about buying individual lights and figuring out a mount for them all, set up the way I just described. Using LED driving/fog lights, my cost was into the $800 range. So, I would be VERY interested if you could do something like this for $200 or less and get similar light output.

For now I'm basing the design off the measurements I took off of my BX, the different sized ROPS would be problematic in this type of design. I don't know whether it's better to just oversize it a bit or go to a more "clamp" style that might accommodate more than one size. I'm trying to run all of the wires internally so they stay protected and resin potting all the LEDs so they are waterproof but the two pieces that come apart around the ROPS need to plug into each other somehow. I ordered a few different sized plugs to try and get an idea of what I can get to fit.
