I ordered my 4410 with a single, rear-facing worklight mounted on the inboard side of the rops on the left side of the machine. There is a hole there that the wires run through. The wires continue down inside the rops and plug in to the black & purple plugs at the other end. Last week I added two forward-facing worklights using only the parts that came in the kit from Deere. It's as simple as this: Unbolt the rear light unit from the rops, slide the brush guard/worklight bracket between the light unit and the rops, put the bolts back in. During that process you must also insert the bolts that will hold the worklights from inside the bracket pointing up. The limited space between the flasher and the bracket will hold the bolt in place. Don't plan to install the bolt from above with the nut between the flasher and bracket, as in the instructions. It will not fit! Next, place the worklights on the up-facing bolts and install the nuts. I aimed my lights horizontal and slightly outward. The last thing to do is to run the black & purple wires down through the rops. I taped mine together with electrical tape and a short piece (3") of baling wire at the leading end. It will take some patience to snake the wires through the hole at the bottom end of the rops but you can do it if you're patient. There is no need to remove the wheels. Once you're through, just plug the ends in to the plugs that Deere has already installed for you. If you've already got a rear worklight installed, as I did, you will have to tap in to one side with the clips included in the kit. If not, just plug in. The only addition I made to the kit was wire wrap on the exposed wires going from the lights in to the rops, cinched down with wire ties, and a few more wire ties to hold the wire wrap to the tractor here and there. I'll try to get some pictures today to post later on. It's an easy project if you have the patience. I don't know what I would have done without those lights this week. Monday night I was out plowing a yard for our cattle to get from the run'in to the water trough and ended up with 10' high piles of snow all aroung after clearing a 30x30 area! We've had over 40" of snow this week on Cape Cod. Needless to say, my neighbors love me now! So far I have a cake, a watercolor painting of me on my tractor from an art teacher, a bottle of Johnnie Walker Black and a bottle of Drambouie fore my efforts!
