Review on Tow Ready 20142 7-Way Flat Pin to 7-Flat Plug Adapter - Regular Plug by Kyle Ziegler

If you want to replace your trailer bulbs with LEDs and your Euro tractor is equipped with an automatic bulb burn test and dashboard warning system. This is a 7 pin adapter that needs to be installed between your vehicle and trailer connector to bypass the 'lamp off' feature. The LED lights are not drawing enough current and the 'bulb out' function reports that the LED lights on the trailer are burned out without an adapter plug on the dashboard.
