I was going to do the same thing on my 2601, but main after dark use was snow removal with either my dozer blade or loader bucket. I clamped a short led light bar I had laying around and tested it only to find all it would light was the backside of either implement. Mounting on the very top bar of the grill guard helped but just did not look right.
However if you decide to go that route I had found a curved 12" led that would have looked really good mounted between the uprights on the guard.
In my case ended up installing a single 18" led bar facing forward on the ROPS and two rear facing square led's. Works great for night time snow plowing.
