how to flip glyphicon icon

Is there any way to flip glyphicon. I found Flip an Image css trick, but that does not work for glyphicon. Please any suggestions

Like this

HTML

<a href="#" class="btn"><i class="icon-rotate icon-flipped"></i></a>

CSS

.icon-flipped {
    transform: scaleX(-1);
    -moz-transform: scaleX(-1);
    -webkit-transform: scaleX(-1);
    -ms-transform: scaleX(-1);
}

OR

Using glyphicons managed to make this work like so:

HTML

<span class="glyphicon glyphicon-search" id="my-glyphicon"></span>

CSS

#my-glyphicon {
        -moz-transform: scaleX(-1);
        -o-transform: scaleX(-1);
        -webkit-transform: scaleX(-1);
        transform: scaleX(-1);
        filter: FlipH;
        -ms-filter: "FlipH";
}
