The line from the 7-pin connector to the left tail light is not permitted in the area of German and Austrian traffic regulations. It has only five veins instead of the required six. The power supply for the right tail lamp (terminal 58R) is tapped parallel unduly from the left tail light (terminal 58L). In case of failure of the left tail lights circuit, the right tail light goes out. This is not permitted according to traffic regulations and at the same time a weak point in the security.
Would the manufacturers use a six-wire lead, there would not be a problem. This restriction of the article must not be used as a kit for fixed wiring of a trailer. Tail lights have left and right always have separate circuits. That is not in this product Fall.34
