If your running lights are not working with the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 but your turn signals are, the issue is likely the diodes. If the wires are not properly routed with the diodes, or there is some issue where a wire was somehow crimped or damaged then the running lights would not work.

You need to create a jumper wire and attach the diodes that way, which may have been the problem so you should check to make sure you have your diodes properly installed.

I have added a link to a help article on installing diodes on a dinghy with combined wiring that I recommend taking a look at.
