Compatiblility Using A 7-way Trailer Connection For Tow Lights And A 4-Way For Trailer Dolly Lights

Question:

I have an RV with a 7-way connection on the hitch. I also will be pulling a tow dolly that has a 4-way connection for the lights. I am looking at purchasing the Roadmaster Standard Magnetic Tow Lights # RM-2120. I would like to plug in the wireless lights and the tow dolly trailer lights in together, so that lights work for both. Is there an adaptor that I can purchase so I can do this? Thanks

To install the Roadmaster Standard Magnetic Tow Lights # RM-2120 you will need the Hopkins Endurance Multi-Tow Twist-Mount 7-Way RV and 4-Way Flat Trailer Connector - Vehicle End # HM40920 for your RV Connection. If you don't have the right connection when swapping your 7-way on your RV, then you will need the 4' Pigtail Wiring Harness for Pollak Replacement 7-Pole RV Socket # PK11998.
