5.0Volkswagen Atlas With high efficiency led trailer
The trailer with high efficiency led lights did not work properly with the Volkswagen Atlas 2020. The leds would hyper flash or not work at all. The car senses current and expects normal lights. With this pigtail it works perfectly. Plug in pigtail, start car and then connect the trailer. Test the indicator signals and you will see the dash show <1> blinking to show the trailer lights work. The car will let you know to check the trailer lights otherwise.
