I don't know why I waited so long to install the Hella Micro DE fog lights, these things are great! I bought what I thought was an aftermarket kit, but it came in a Toyota Genuine Parts box. All I did was install the brackets and lights, plugged in the included relay and tapped two wires under the steering column for the switch and they were done. SR5's are prewired for fogs from the factory.
I also re-did the cargo light with LEDs. These put out a little over 6X the light as stock.

After, without the lens cover:
Note the difference in brightness between this light and the stock passenger area dome light.
The stock rear dome light was useless for finding anything at night. In fact, I tried to photograph the stock light output and it was so dim you couldn't hardly see anything in the photo. I used twelve LEDs in the rear--probably should have used ten...it's a bit overkill. I will probably use six in the front one when I get around to it.
It was 103 degrees here...I think I drank 2 gallons of water while working on the truck!
