1. A wedge-base bulb socket structured for supporting a light bulb having a glass bulb which ends in a substantially wedge-shaped plug housing the ends of the two rheophores which feed electric current to the filament housed inside the bulb, the wedge-base bulb socket comprising: a supporting base provided with a coupling seat dimensioned to house the wedge-shaped plug of the light bulb;two coupling and connecting members located inside the coupling seat, and structured to separately clasp the wedge-shaped plug of the light bulb fitted into the coupling seat, and to feed electric current to the ends of the rheophores of said light bulb; andelectricity supplying means connected to both coupling and connecting members and structured to feed electric current to said coupling and connecting members;wherein the electricity supplying means comprise two electrically conductive elements which extend on the surface of the supporting base up to the edge of the entrance of the coupling seat, on opposite sides of said entrance, and then descend into the coupling seat to reach each a respective coupling and connecting member; and two reciprocally-facing additional supporting jaws which are supported by the two electrically conductive elements so as to be located substantially on opposite sides of the entrance of the coupling seat, and which are structured to clamp the wedge-base light bulb fitted into the socket, to firmly hold said wedge-base light bulb in the wedge-base bulb socket. 2. The wedge-base bulb socket according to claim 1, characterized in that the two additional supporting jaws are made of a material having a high heat-dispersion capacity. 3. The wedge-base bulb socket according to claim 2, wherein the two additional supporting jaws are made of a metal material. 4. The wedge-base bulb socket according to claim 2, wherein the two additional supporting jaws are made in one piece with the corresponding electrically conductive elements. 5. The wedge-base bulb socket as claimed in claim 1, wherein the two additional supporting jaws are structured to clamp the neck of the wedge-base light bulb fitted into the coupling seat. 6. The wedge-base bulb socket as claimed in claim 1, wherein each electrically conductive element consists of a metal-material strip which extends on the surface of the supporting base up to the edge of the entrance of the coupling seat, and then descends into the coupling seat to reach the respective coupling and connecting member. 7. The wedge-base bulb socket as claimed in claim 6, wherein each additional supporting jaw consists of at least one centering and clamping lug which protrudes from the metal strip, immediately above the entrance of the coupling seat, and is shaped so as to rest on the wedge-base light bulb fitted into the socket. 8. The wedge-base bulb socket as claimed in claim 7, wherein each additional supporting jaw consists of two centering and clamping lugs which protrude from the two lateral sides of the metal strip, on opposite sides thereof, immediately above the entrance of the coupling seat, and are arched so as to rest on the wedge-base light bulb fitted into the socket. 9. The wedge-base bulb socket as claimed in claim 1, wherein each coupling and connecting member is made in one piece with the respective electrically conductive element. 10. The wedge-base bulb socket as claimed in claim 9, wherein each clamping and connecting element comprises a pair of parallel and reciprocally-facing fastening and contacting tongues made of an electrically conductive material and which are arranged parallel and faced one another so as to form the two jaws of a clamp having a shape complementary to that of the plug of the light bulb; the fastening and contacting tongues being made in one piece with the corresponding metal strip. 11. The wedge-base bulb socket as claimed in claim 1, wherein the supporting base is provided with a protruding collar which forms the entrance of the coupling seat. 12. The wedge-base bulb socket as claimed in claim 11, wherein the two electrically conductive elements consist of two metal-material strips, which are folded in a substantially a substantially upside-down U shape, and are straddled on the edge of the collar so that each metal strip has a first branch at least partially adhering to the internal surface of the coupling seat, and a second branch at least partially adhering to the external surface of the collar; the first branch of each metal strip extends inside the coupling seat up to reach the corresponding clamping and connecting element; the second branch of each metal strip extends up to reach an power-supply electric circuit arranged on the supporting plate. 13. The wedge-base bulb socket as claimed in claim 1, wherein the two additional supporting jaws and the two electrically conductive elements are made of bronze for springs, steel for springs, stainless steel, or phosphor bronze. 14. Automotive light for motor vehicles and similar comprising: a rear body which is substantially basin-shaped, and is structured so as to be recessed inside a specific compartment realized in the vehicle body;at least one light source which is located close to the bottom of said rear body, and is structured to emit light when electricity powered;a front lenticular body which is made at least partially of a transparent or semi-transparent material, and is arranged to close the entrance of the rear body to be crossed by the light emitted by said at least one light source; andat least one wedge-base bulb socket,wherein the at least one wedge-base bulb socket includes (i) a supporting base provided with a coupling seat dimensioned to house a wedge-shaped plug of a light bulb; (ii) two coupling and connecting members located inside the coupling seat, and structured to separately clasp the wedge-shaped plug of the light bulb fitted into the coupling seat, and to feed electric current to the ends of rheophores of the light bulb; and (iii) electricity supplying means connected to both coupling and connecting members and structured to feed electric current to said coupling and connecting members;wherein the electricity supplying means comprise two electrically conductive elements which extend on the surface of the supporting base up to the edge of the entrance of the coupling seat, on opposite sides of said entrance, and then descend into the coupling seat to reach each a respective coupling and connecting member; and two reciprocally-facing additional supporting jaws which are supported by the two electrically conductive elements so as to be located substantially on opposite sides of the entrance of the coupling seat, and which are structured to clamp the wedge-base light bulb fitted into the socket, to firmly hold said wedge-base light bulb in the wedge-base bulb socket.
