Check all the lamp sockets on that circuit and check the bulbs themselves for broken but not burned filaments.
If the socket has broken tangs inside, replace it.
If a bulb is faulty, replace that bulb.
Thoroughly inspect the lighting harness to make certain that it isn't damaged somewhere.
Then let us know what you found.
