I do notice that the 3 tabs that you have to insert a certain way into the fog lamp, those tabs are smaller than the current light. Not sure if that has anything to do with it but both of my replacement sets (from 2 different companies) are that way
The only way I know of is to get thicker O-RINGS. The tabs on the bulbs should be the same size and in the same location on all the bulbs.
You have 3 different bulbs to compare, so you should be able to see what the difference is between them.
I had to put the O-RINGS from the 9600 Halogen bulb on my 9600 HID bulbs to make them fit tighter.
Hope you figure it out.
