Its not an exact replacement but it fits nicely and looks great. No modifications needed just insert and twist. As you can see its shorter then the Ford OEM bulb but being a green LED it is bright enough it works well enough. A little different green, I actually like it better. I did a bunch of research and IIRC it is from a Mazda dashboard light. They are called Neo Wedge LED bulbs
By the way, does anyone remember/know if the dimmer switch is supposed to light up
New LED light
Compared to the original Fog Light Green
