I just installed GP Thunders in both my DRLs and fogs. The fogs fit fine. However, the fit on the DRLs seem loose. They're seated, but I can "jiggle" them easily, tilting them such that I can easily create a gap between the red gasket and light housing.

Is this normal? The same bulbs seated nicely in the fogs. I am 95% sure I have them properly twisted in and seated. I even took them out, and reinstalled the Osram OEMs to make sure I was twisting them into the right position, etc.

I'm concerned that the loose fit may either eventually allow a small amount of moisture into the housing over time, causing corrosion (happened on my Lexus), or that vibration from driving might actually unseat the bulbs (not likely, I know).

This looseness is on both sides, further convincing me that they are properly installed and that this is a bulb design issue.

Anyone care to comment?
