You could try sending a PM to NSBCruiser. He made some sweet brackets for the OEM roof rack....
Thanks for the props.
ND40oz here is what I did.
I found a Hella Matador Work Lamp on eBay, cheap. I installed it on the rear with a custom made bracket for the factory roof rack. The wiring is ran through the roof rack (like seen on all over this Forum).
The Matador has a built in switch on the lamp, I use that as a master on/off and I have a Tacoma Fog light switch for in cab control.

Picture of the quick disconnect and grommet used for the roof rack. I used a trailer wire two pin connector.
The Hella Matador Work Lamp was really a good choice for my needs. The light pattern is very broad and bright. It is a flood lamp, I was considering installing two but one is more than enough. With the way it is mounted it can still swivel and tilt using the original bracket that came with it and the bracket I made for the roof rack.
I wired it up to three relays. One relay lets me use the work lamp whenever I need it using a Tacoma Fog Light switch, and the other two relays automatically activate the work lamp if the headlights are on and the FJ is in reverse, these two are wired to a older style Tacoma on/off switch (so I can turn on or off the reverse light function).
I found this on a Land Rover forum and modified it to work with my application. I turned out fantastic.
I know, I know... Land Rover, but I sold my 2002 Discovery II for my FJ... I still have a soft spot for Land Rovers
