This adapter converts a 7-blade vehicle connector to a 4-flat trailer side connector. Its Nite-Glow function checks to see if you are getting power from the tow vehicle, and confirms you have installed the adapter properly. If the connector glows red, you have a solid connection. Also, includes dust cover for 4-Flat to help prevent corrosion.
