Today, we're going to be taking a look at part number 78117. This is the Reese Trailer Connector Adapter with Tow-Glo LEDs. It's going to be a 7-pole to 4-pole flat adapter, so this is going to allow you to convert your 7-pole round RV-style connector, which is this portion right here. It simply just plugs in to the existing connector on your vehicle, and now you're going to be able to convert it to a 4-wire flat vehicle-end connector. The 4-way flat connector has a nice dust cap on it. It's going to protect the connection points from the elements. It's going to let you to tow a trailer with a 4-way flat plug.

This will work when it comes to adapting any RV-style 7-way round plug, and it's going to connect your ground, left turn, right turn, and stop circuits. Now, located on the inside of the plug is going to be a highly visible blue Tow-Glo LED system that's going to make the connector easier to see in low-light conditions. The LEDs are going to be activated by your vehicle's taillight circuit. This unit is going to give us an overall length, measuring from edge to edge, a four and one quarter of an inch. Now, I want to go ahead and connect our external power source. That way, you can see the blue LEDs located on the inside here.

You can see there, it's a nice consistent signal. The clear design allows a lot of the light to come through, which again is going to increase visibility in low-light conditions making it easier to see the plug and to make the connection as necessary. That's going to do it for today's review of part number 78117. This is the Reese Trailer Connector Adapter with Tow-Glo LEDs for 7-pole to 4-pole flat connectors. .

Do you have a question about this Wiring?


  • No Trailer Lights Using Adapter 7 Pole to 4 Pole # 37335
  • Adapter 7 Pole to 4 Pole # 37335 isn't fused but it is possible that something happened to the wiring on the inside. I recommend taking it apart and inspecting the wiring and fix as needed. Or replace it with a different adapter such as # 78117 if you still want one that lights up. Or for a regular adapter # PK12716 is a popular option.
