Headlight condensation sealing

I recently purchased new headlights for both sides of my 2012 E92 and am noticing a little condensation inside the light. My car is not under warranty so I was wondering if anyone know a Chicagoland / NWI shop or DIY solution on how to fix this problem?

Purchase some silica gel/desiccant packs and place them inside the headlight secured with some tape so you can get them back out as needed.

I fight the same battle with my Lexus, but this keeps them dry inside for most of the year and is a very cost effective solution.

It didn't work for me the new headlights i brought needed to have the vents in the back opened to let the moisture out. The bulbs ended up burning out.

Zach, to fix this issue how silica gel packs should someone put inside the headlight? for how long we should keep it inside with headlight with cover on?

I used tape and place it inside. As a matter of fact, I never take it out. Fix it

As Ruiz suggested, I also used tape to secure the packets in the lights of my old vehicle. I never took them out either. I would replace them as needed with new packs. I typically put 2-3 smaller packs inside the light at a time.

I had this issue after I retrofitted mine. Drilled a small hole on both caps and stuck a breathable membrane on top of it to seal it, the membrane allows it to breath and since then I haven't had any issues. I experience all extremes for weather here in New England. I got the membrane sticker from Bav Gruppe

Bought my 2011 8 months ago and noticed the last time I washed the engine bay the passenger side fogged up. Good to know it's normal even on new lights. I'll try the silica packs next time it bothers me.
