Recently had Minor collision with a parking post, and cracked the lense on my PS headlight. Yesterday, it was raining pretty good and I saw the PS light turn on and off several times, but then stayed on. Today, when I got home, the DS Daytime Running Light wouldn't turn off. I waited like 5 minutes. I disconnected the battery to save it. I also noticed that the PS headlight was not working.
What can I do to fix this issue besides taking it to the dealer?

Turns out it was a failed LED module, due to a cracked headlight housing, which allowed water to enter the headlight.

NOTE: When replacing headlight LED modules, there are many different versions (letter suffix on the PN) that must match the vehicle. I bough one off eBay from a a Ford Dealer, who didn't specify what option the module had. The module I bough was for "autoleveling" headlights. My Expo didn't have that option.
