Fog lights work only sometimes.

When I bought my truck the fog lights did not work. I didnt think much of it, I bought led fog lights and they worked fine. I was washing my truck then later that day the fog lights were not working, after I took a close look, inside the connector was wet. I let them dry for a day or two put them back in and they didnt work. A couple days after that I put them back in to find they were working perfectly. I was going to wash my truck again so I took them out, when I put them back in they are not working anymore. I checked the fuse and I tried them on both sides.

 

I'm going to try very hard not to sound like a wise ass here. Your problem is most likely the cheap Chinese LED's you are using. Try putting the OEM (or OEM equivalent) bulbs back in and tells us what happens.
