some may consider this ultra OCD - but I taped a few of these inside each lens.

I got mine from a shoe-box when I bought shoes a few months ago.

Now when moisture appears, it dissipates quickly.
Keep in mind--this is not an airtight design (new gaskets or not).

Also note---I've always noticed that immediately after opening these, moisture is present for a few days after---until it is burned off by the heat of the bulbs

Could there be an installation error? Becuase I changed the lenses on both lights (came from ECStuning) but only the driver side leaks. It's been about 2 days since I replaced the gasket. Does the gasket need heat to bond?

I've had my headlamps open when I modified my high beam mirrored lens. I didn't change my gaskets I performed the modification, but I did make sure to heat the gasket, and lens prior to installation.

I used a hair dryer and about 30 minutes a side to ensure the gasket was nice and warm and then pressed the lens into the gasket.

I have no moisture... Not sure if that actually helped, but thought I would share my experience.

It's called a fish tank, the only reason I don't change to aftermarket clear . It simply happens. https://forum.e46fanatics.com/showthread.php?t=1101309

Usually when replacing lenses gaskets it's good measure too also replace lenses it's self, keep in mind housing may have been worped or original lens may have an unnoticed Crack.

My nonsense information to keep in mind!
