An opening is stamped into the sheet metal plate corresponding to about the diameter of the light bulb socket in order to allow insertion of the light bulb. The guide flaps for the light bulb socket are cut from a region of the sheet metal plate which is outside of the opening for the passage of the light bulb socket. The guide flap is bend around two axes vertical to each other such that the end sections after an arcuate shaped deformation form part of a circular cylinder shaped jack.
