cb919 headlight problem

[HornetBoy]

okay so heres the story:

Got some new zorsts for the hornet and strted to put them on -to get ready for this i took off the seat ,side panels,rear panels and disconnected out rear light ,indicators and number plate lights.Put on the zorsts all fine and dandy and put everything back in its place but when i turn the bike on the headlight isnt going grrr (because i know ive seen a thread with this same problem a while back but i cannot find it .) but the headlight does go when i put it onto high beam ..so thats my problem ,how do i get the light to work just on normal beam

now ive checked all connections and im pretty sure i havent left aything undone .. very frustrating

So if anyone could shed some light on this for me id greatly appreciate it!!

1 = Blown bulb.
2 = faulty high - low switch

why would it suddenly not go on low beam but still work on high? it worked before i changed the exhausts... all i can think was i pushed something out of place when i was fiddling around to undo a bolt .but i still dont know where the headlight low beam wire is in the rear of the bike to check if i have...
