if you take an H7 glow bulb, you'll see that there are 2 glow wires, 1 for low and the other for high.
ok, you can more or less create that effect by with a highbeam mirror, like in the buell.
if you want 2 burning light without highbeam, you need a 2nd lowbeam mirror for the 's' and for the 'r' you need to complete lowbeam assembly.
