Used to bypass signal from the car so it could not “see” the led-trailer lights. The video shows the issue that was solved

Ce petit boitier est fonctionnel. Mais aucune information n'avait été donné concernant d'éventuels frais de douane. 14€ pour un article à 32€, c'est plus de 40% du prix en plus ... Pas mal. A fuir !
