If the bulbs are parallel, I think they are, then the answer is a wire has come off somewhere that powers the ambers. This is an Attitutude Toy Hauler w/o a wiring diagram. I contacted the Company, in part: power travels first to Driver side front upper then L side marker, over to front R upper then R side marker. The power loss has to be between the front driver side upper and the junction box.I don't know gauge or color. I tried to remove a marker but they are packed solidly behind with a mass of putty? Which I don't want to disturb. No time now to dig further off to MTRe: Amber side markers are not operating.Thank you Bedlam for your post, will follow the harness back and find out why the ambers aren't operating. Question, don't know the term , but if one bulb is out, would it affect the entire light system, reds, tail lights or would it just be the individual bulb. Don't know where the splice box is, but the fuse panel below frig is a jumble of wires....does the slice box go through the fuse wall area? Or are the driving lights fused off truck?Amber side markers are not operating.There is 12 volts coming from the truck for on the same circuit are the tail lamps and red markers which are working. I checked all 4 ambers bulbs with a continuity meter and they are good. I have no electrical diagram with the Toy Hauler. Suggestions?
