How Does Trailer Light with One Wire Connect to Two Wire Wiring

Question

Question:

old RV traveling light has 15 amp small bulb built in with only one black wire. The current one I am removing that is broken has a white ground? and a black wire. The two wires are currently wired together into a yellow electrical nut which has the same 2 colored wires twisted into the yellow nut on the receiving end. Is it okay to use the newer travel light fixture which only has one black wire?
