They are seperate bulbs - dipped is on the left and full beam on the right as you sit on the bike.
I *think* that one is an H1 bulb and the other an H4 bulb, but please check with the manual before you go and buy them as I might be wrong.
Getting at the bulbs is a royal pain in the arse as the leads are usually tucked away behind the headlight bucket (the metal casing) making changing them on the bike almost impossible. I usually take the top fairing off (4x dzus, 2x allen and the mirrors) and then take the headlight unit out (undo the adjuster bolt and then slide it out) to do it as it makes it much easier.
This might be a good time to buy a Haynes manual....
