Yeah my bottom third of both lights are fogged up, just noticed this when I picked up gas. What caused me to look was when I was on the highway, the light was going from the normal white to a yellow hue. I thought I had something on the front of the truck. Not sure what is going on, no warnings or codes when I plugged in a reader. Going to call the local dealer (out of town for the weekend) and see if it something that needs to be fixed right away, or I will wait until I get home and bring it to the dealer I bought it from.
