Hey Third Horseman...
I purchased a set of fogs from blinglights.com (via ebay).

eBay Motors: 2003-2007 Toyota Tundra Halo Fog Lamps 04 05 06 lights (item 130160681406 end time Oct-12-07 12:07:23 PDT)

I just followed the instructions posted on the forum posted by Doooode.

The lights fit well in the factory location. I just have to run the switch into the cab yet.

In Doooode's post he mentions the few flaws: (fabricate the mounting bracket, extending the wiring between the lights, and to the switch, but besides that, the lights compliment the truck nicely. Just make sure you get all the parts you need in the beginning, - aluminum, bolts, washers, nuts, extra wiring, and either butt connectors or your soldering gun, and plenty of wire lume and wire ties.). In a few days mine should be fully functional.

Best of luck!
