You're looking for a plot line. See the documentation here: http://api.highcharts.com/highcharts#xAxis.plotLines.

The basic format is:

xAxis: {
    plotLines: [{
        color: '#FF0000', // Red
        width: 2,
        value: 5.5 // Position, you'll have to translate this to the values on your x axis
    }]
},
