headlight lo and high beams not working

[miller.connor25]

so I have a 2003 gz250 and it's totally stock but the headlight just went off during a ride and when I got home I checked it out and all the fuses are ok the bulb turns on when connected to a battery charger the high beam light is always off but it came down to the high/lo beam switch on the handle bar and I took that apart and used the battery and some wire and touched the wire to the battery and the other end to the wire in the switch and the light came on so do I have to replace the switch or the whole assembly around the handlebar that includes the blinkers and choke
