99% of the time it's a pin alignment issue from installation. Again, we will make sure you are taken care of, but the metal pins on the bulb have to be making contact with the tabs in the base of the socket to function correctly.I have the switchback on the passenger side that flickered the other night and now is out. I'll check it out when I get a chance. Will put factory yellow back in socket to be sure it isnt a socket issue first.
