I noticed when I was plowing the other day there weren't any lights on the rear of the tractor. When I would backup I would have to rotate the light bar that I put on my ROPS to point to the rear then move it to the front when I was done.
I bought a set of lights from Amazon for $22 that ended up being better than I had hoped for. For now I wired them into the cigarette lighter but plan on moving them to a more hard-wired solution. I will however put them on a plug and keep them removable because I now see these my have more utility than just using them on the tractor.
There are two four inch lights like this in that box:
Instead of hard-point attachment for these I chose to go back and use some of the magnets I bought earlier in the year to hang tools on the tractor with. I felt this would give me more options if I needed light elsewhere I could easily move them without tools. It also meant I didn't have to drill into the ROPS or worry about them getting taken out by a limb. On magnets they will either slide out of the way or fall off AND GET CAUGHT BY THE VELCRO LOOPS that hold the wiring loom in place.
Here is a closeup of one of them assembled and stuck on the ROPS:
I also discovered last night that with the spreader on the tractor the hopper was so big that little to no light was getting behind it. Since it is a metal hopper...problem solved!
The other advantage I see is that these can easily be moved into another vehicle. No reason that they can't sit on the hood or roof of a car and be used for additional lighting in the yard. They would work well on a bed side-rail to illuminate the contents of the bed as well. All in I have less than $40 and about 1 hour of time into this setup.
