Yes, when I had my new bumper built the builder supplied a pair of LED lights that were fitted to the bumper.
Wiring couldn't have been simpler: He unplugged the fog lights, then I think he had to splice in a connector to the LEDs, and then plugged them in. Easy and totally reversible if I want to.
Don't have a picture with the lights turned on but here is what they look like:
They work perfectly with the stock switch on the turn signal stalk. Not sure how they compare bright-wise, as I haven't taken the 4runner off-road since I got them. I also have not (yet) done the independent-fog-light mod (that will allow me to run the fogs without the headlights on.)
