Cable branch for converting a PX with E-Start to LED headlights. The cable branch is suitable for all PX E-Start models from 1984 to 1998 with a light switch with 9 cables. This simple conversion uses the existing circuit of the existing battery. The adapter is inserted under the cascade between the light switch and the plug strip of the wiring harness. Thus, the electrical conversion to DC (direct current) for the driving light and thus the use of a modern LED headlight can be implemented with just a few simple steps. All functions of the light switch are retained. Together with the Moto Nostra LED headlight a nice conversion to constant bright LED light, without the usual brightness fluctuation at low speeds in AC operation. No conversion of the ignition system is necessary. With the ignition on, the light can be turned on without the engine running. Due to the adapter solution used, the conversion can be reversed at any time. A useful addition is the appropriate plug set for the headlight. With the plug set, the desired LED headlight can be connected to the existing light switch without having to change the light switch.
