Hey Dale,
There isn't an adapter like this already made but you can easily make one yourself. You'll want the # 7-Way RV to 4-Way Flat Trailer Connector Adapter # HM47365 and some load resistors # DI34ZR. You can either unscrew the 7-pole plug and disconnect the wiring or just cut it in the middle since you're going to be extending it a bit.
Using some spare wire # 16-4B-1 you'll splice the resistors in line with the light function wires with some heat shrink butt connectors # DW05744-10. I would try to cut the wires so that the resistors are staggered and aren't all bunched together. You can then wrap it all up in some electrical tape. You can then plug your adapter in and connect your LED Light Bar # HLY54RR.

Hey Dale, how did your wiring project go with the adapter and resistors for the Hollywood bike rack lights? Your results could really help others trying to get their LED light bars working the same way.
