One of my headlights from my older e90 gets water droplets on the front inside of the headlight when is rains and now as it is becoming winter it also has this water constantly because of the nightly condensation. I am wondering if the headlights seal is just some screws that might need tightening or would it be something like a silicon seal that requires the headlights to be replaced.

Most of the BMW headlights I know of are glued together, no screws. I might suggest as a first thing to check is the little access door used to replace the bulbs. They are held on with plastic clips that can break or come loose, and cause a leak in the otherwise watertight housing.

If you do find it's not closed completely, wait for a nice hot day so all the moisture is evacuated, then close it up again. If the clips are broken, you might find a replacement door at the local junkyard.

Get urself some RTV take the headlight out and put a bead around the whole lens. As well as the acsess ports for bulbs. Change all the bulbs before you do this so you dont have to remove the rtv if a bulb goes.
