RV Repair: RV Top Running lights, continuous circuit, interior ceiling

Question
Have a 23' 1987 Tiroga Class C Motorhome, It's in great shape except for the front and rear top running lights. Only one in front and 2 in rear are working. Seems they have lost connection in both + & - mounting studs. Can't figure out how to repair. would you have to remove interior ceiling to get at back of mounting/terminal studs? Thinking of building a custom light bar and mounting both front and rear. Is their an aftermarket assembly available?

Answer
Just get yourself some aftermaket running lights all the way around. Unless I am not understanding your question, the light fixtures are bad. It could also be that there is a bad wire somewhere. Most clearance lights are wired in a "continuous circuit" if that helps any.
