So yeah I'm an idiot, I changed my D4S bulb and I was in such a rush I forgot to put back on the little door, now my headlight has little running water and foggy inside. How do I fix this? fml...

 

Remove bulbs, let it evaporate (or help it with a blow-dryer), then put the bulbs back in and put the cover back on.

Do you think that might cause the bulb to flicker/not work sometimes?

 

hmmm sounds like you're using the wrong bulb causing the flicker... use a heat guy not a blow dryer cause the water will never evaporate fast enough.. after drying let the car sit overnight and double check it the following morning.. better to park it in the garage

 

I'm running the OEM bulb on it right now thats flickering and shutting off.

 

Put silica packets in there afterwards for good measure
