THE PRESENT INVENTION RELATES TO A LIGHTER (10,90,100,114) WHICH A USER ACTUATES BY AT LEAST TWO DIFFERENT MODES OF OPERATION. IN THE FIRST MODE, A BIASING MEMBER (42) IS POSITIONED TO OPPOSE MOVEMENT OF AN ACTUATING ASSEMBLY SO THAT A USER RELEASES FUEL (21) AND IGNITES THE LIGHTER. (10,90,100,114) ONLY IF A HIGH-ACTUATION-FORCE IS APPLIED TO THE ACTUATOR. IN THIS FIRST MODE, THE LIGHTER (10,90,100,114) RESISTS OPERATION BY UNINTENDED USERS BY REQUIRING A USER TO HAVE A PREDETERMINED LEVEL OF STRENGTH TO ACTUATE THE LIGHTER (10,90,100,114). IN THE SECOND MODE, THE BIASING MEMBER (42) IS MOVED TO A DIFFERENT POSITION WHICH DOES NOT OPPOSE MOVEMENT OF THE ACTUATING ASSEMBLY TO THE SAME EXTENT AS THE FIRST MODE SO THAT A USER MAY RELEASE FUEL (21) AND IGNITE THE LIGHTER (10,90,100,114) IF A LOW-ACTUATION-FORCE IS APPLIED TO THE ACTUATOR. MOVING THE BIASING ELEMENT (42) FROM THE FIRST POSITION TO THE SECOND POSITION PREFERABLY REQUIRES THE USER TO HAVE A PREDETERMINED LEVEL OF COGNITIVE ABILITIES AND/OR PHYSICAL CHARACTERISTICS IN ORDER TO RESIST USE BY UNINTENDED USERS.
