Here's a thread on the fog light deal, and there are about a half dozen on reverse lights:

On reverse lights, maybe it would be different if I had a backup camera, but I doubt it, because other guys WITH backup cameras have said the same thing. There's more than one reason that the OE's use halogen bulbs in fogs and reverse lights. Sure, it saves cost, but there simply isn't a viable option for useable light output (lux) right now that is much "whiter" in color than the factory halogens. You can go a little bit higher color temp on a halogen, but in my experience once you get much above 3200-3400K, even on a halogen, the "whiter" you get, the more lux you lose. There are 3800K, 4000K and 4400K halogen bulbs, and most LED's are in the 5000-6000K(ish) range. That's why they all look so whoop-a$$ in cell phone pics, or when you're looking right into them. But make no mistake, it's an APPEARANCE "upgrade".
The best results I got from a reverse LED bulb is the Putco "Plasma" - which basically matches the style and technology of their Optic 360 fog light bulb. Pretty good, but still not as much useable light looking in to the side mirrors on my truck. Same with the fogs....much "brighter looking" in a picture or staring at the front of the truck, but about 30% less lux at 10 meters than the 3200K halogen bulbs.
And I have some foglight bulbs for sale if anyone is interested. I upgraded mine to "off-road" LED.
