The Nissan Path

I put led 3157's in my parking lamps on my 2006 Path and I found that my lamps are not functioning anymore. I put my factory bulbs back and still nothing. Turn signals still work but nothing when I put my parking and head lights on. Checked fuses and nothing's blown.

Using a meter or test light check for power on both sides of the fuse socket and at the light socket. I personally would start at the fuse since it's easier to get at but at-least you'll rule out a lot of possibilities with those 3 quick steps.
