LED Fog Lights Stage 2 & 2.5

Hey Paul, I was looking for more info on these new updated fog lights from your website. What's the difference between the o.g. LED's, the stage 2 and the 2.5?

I have your SMD AEs in white, as well as the HID low beams 6000k, and my original DD Fog Light LED's get pretty much washed out. I was looking for a brighter foglight without going to the Fog Light HID setup. A brighter plug n play LED would be awesome for my needs..

Thanks!
