I have no idea bro.
Check your fuses if you know how

If you dont, call up infiniti and they should be able to come to your house and fix it.

 

Check your fuses, changing out lights and doing other minor electrical work without unplugging the battery always runs the risk of blowing a fuse or 2...you were just unlucky that it happened to you.
Not a big deal though...just check all your fuses and replace any blown ones.
