TTR600 Headlamp high/low beam wiring
 

Hi there, wondered if anyone could point me in the right direction of a replacement part for the high and low beam wiring between the switch and the bulb (what I can best describe as resistance wiring enclosed within a heat resistant material sheath) ..It got fried on a trip and I've done a temporary job on it, but I'd like an original part, or a better alternative if anyone knows of one.

I've tried several searches for it, but I'm not really sure what it's called, which leaves me somewhat handicapped...

Many thanks!
