The ornamental design for a lighter, as shown and described.
FIG. 1 is a perspective view of a lighter showing my new design;
FIG. 2 is a left side elevational view thereof;
FIG. 3 is a right side elevational view thereof;
FIG. 4 is a bottom plan view thereof;
FIG. 5 is a front elevational view thereof; and,
FIG. 6 is a rear elevational view thereof.
Both of my disposable and electronic lighter body has a hole in the body. Having a hole in the body of the lighter makes it easy to carry. It can also be easily hung on a hook of a wall which is quickly found during times of emergency. And it is cool looking too.
