Next thing i did was to interchange the original (bulge) Headlight for a "traditional" design.
However... The The turn indicator relais is located within the Headlight and originally is protected against vibrations, by a rubber mount.
I thought it would work also by just "cram" it behind the reflector (at least for a day or two...)
I fried it..or shaked it to death within an hour or two.
Have to replace it asap. This time, taking care of a proper place and mount.
