I ran mine in the 3500 range for the first 20 hours in low range as well.

Painful for sure, but I am a firm believer in doing a proper break in. I was bird hunting up some logging roads so I was able to vary the speed and have several cool down periods.

I just bought a UForce 600 and was looking for a fix as well. It turns out that my bike (Canadian version) is already wired for a backup light with a 15amp fuse and relay, just no light. Just by the tail lights there is a yellow wire with a bullet connector that's not connected to anything.

I connected my light to this wire and by golly it comes on when I am in reverse. Since there's no room for an additional light on the back of the bed, I am mounting two small led lights above the rear window and routing the yellow wire to them.
