Well the iJDMToy LED Fogs came a lot sooner than expected and I installed them today. I can confirm the adjuster should be pointing down, how can I be sure? I fired them up with a 9 volt before installing them in the car. When the adjuster is pointed down there is a nice horizontal cut off line at the top and a round shape of light at the bottom. This applies to the white and the yellow. You can see in the pictures what I mean. All pictures are sitting on the same
coffee table in the same place. The only difference is whether the adjuster is pointing up or pointing down.
Here is the nice horizontal line with the adjuster pointed down.
