ABSTRACT:
The safety lighter includes contact wheels requiring rotation to rotate a spark wheel for generating a spark and, hence, a flame in the lighter. An extension, preferably part of the windscreen, includes a top wall overlying the majority of the circumferences of the contact wheels. Only a small portion of the contact wheel surfaces are therefore exposed for engagement by a user's thumb, thus increasing the strength and dexterity required to actuate the lighter and inhibiting actuation of the lighter by children.
