2007 RAM tail light issue

Hello everyone. Just bought a used 2007 RAM
1500... without realizing when I drove off, my
passenger side tail light is out. Replaced the
bulb...still nothing but the brake and turn signal use
the same bulb both work.  Just no running light
Anyone else encounter this issue and if so, I would
appreciate any suggestions...gonna take it where I
bought it since they took it for inspection before I
picked it up and in most states...the tail lights need
to properly work for it to pass
