I had switched my bulbs to leds and found out the the covers on low beams didn’t fit so I ordered the taller ones to fit put them on and the lights still get fog and condensation in them. Any thoughts or fixes for this?

If they weren't fogging before, then the problem is probably in your install somewhere. I used to work on OEM headlights, and I can tell you they spend a lot of time on proper venting so that they don't fog, or if they do, they should clear on their own quickly. Usually the bulbs and covers have seals on them that can bind up. You can throw a little bit of dielectric grease on them if they are leaking.

Do I add the grease to the bulb seals and the dust covers?
 
I would put a light coat on every seal. I don't know what they look like, but if they are a hard cover that twists in, they should have some type of rubber seal associated with them. If they don't have this, then that is your leak. Try swapping the seals from the coverrs you replaced. Check the aftermarket wiring too. Sometimes it isn't sealed.

The problem with the aftermarket is, the OEM makes the lights so good, that even if you have a pinprick leak, it will suck water in as it cools. They usually have gortex patches on them to help balance the moisture in the lamp, but they don't cure actual liquid water very well.

If the lamp is actually leaking from Ford, they will usually warranty it, but not with an aftermarket bulb and covers on it.
