components?

On account of the variety of installation situations, the sets only include the basic equipment. However, additional harnesses and installation material is usually listed in the assembly instructions under “Accessories”. These can also be ordered via a retailer or garage.
On account of the different vehicle bodies and variety of installation scenarios associated with this, the attachment bracket for the vehicle sometimes has to be custom-made separately.

e1 is for instance the marking for electronics testing. The daytime running light is not tested for this.
