I am looking at doing ths myself.

What I was going to do was-
(1) Run the work light off a relay
(2) Use a switch with two on positions and one off
(3) Take a feed from the existing reverse lights and run that through the switch
(4) Run a feed from the battery through the switch.

This will allow for the existing reverse lights to operate with or without the work light. Will also allow the work light (and the reverse lights) to be on with the engine running (without the vehicle running away lol). You will also be able to operate the lights with the engine off.

The method you have suggested will work fine but the work light will come on whenever you select reverse. Not a real problem but my neighbours probably wouldn't like it shining through their windows when I'm in my driveway.
You can connect both feeds to the same terminal on the relay. All that it will mean is that you will have the reverse lights on with the work light.

If you have dual batteries it would be a good idea to have the relay power coming from your second one in case you forget to turn it off.

Hope this makes ome sense to you.

Just think it is no different to hooking up spotlights except for the reverse wire connection (and no high beam connection).

Legally you must run lights on back of car off the reverse lights.

Im using some of that coily cable from Jaycar, like phone cord for the power.

I took the power from the reversing lights, cut into the cable there.

Also did the cheap piece of box section and a hella 181 for mine.. Works a treat, adn $130 cheaper than the Kaymar one.

Andrew,
The 2 worklights I have are mounted on the back of my roof rack (it's a permanent addition to my Patrol).
I've wired them together through a 2 position switch and have added a green flashing LED to remind when they're on.
Both position of the switch are "ON".
One position (which I leave it in all the time virtually) makes them come when i select reverse.
The other position is what I use to remind sleepy drivers behind me that they may have forgotten to dip their high beam etc and I also use them when setting up the camper at night.
They are powered off 2nd battery.
I cut a small amount of insulation off the wire of the reverse light and soldered a wire to it. (covered the join with that magic liquid insulation material, which sets like tape). Ran that wire back along the chassis to one side of the switch on dash. Centre pole of the switch goes to the relay "SWITCH" tab. Other "ON" pole of the switch goes to the relay also and joins with the wire from 2nd battery for power in to relay.
Hope this makes sense. It's the same as one of the other blokes has said, except I haven't bothered about a "CENTRE OFF" option; which isn't a bad idea.
