ABSTRACT:
A vehicle cigarette lighter comprises a casing ball-jointed to a plug member which is removably insertable into and thus electrically connectable with a lighter socket formed on the dashboard of a vehicle. A lighting unit comprising a heating device is disposed within the casing to receive and light a cigarette therein. Warning circuits are provided to send off aural and visual signals when the cigarette is inserted into the cigarette lighter. A control circuit is provided to shut off power supplied thereto if the cigarette has been deposited in the cigarette lighter for a given period or the temperature of the heating device has reached a pre-determined level. The plug member has mounted on one end thereof a ring member which has several outward deflected resilient tabs formed by punching or pressing to provide a more secure contact with the lighter socket of vehicle dashboard.
