From Soberlife:

"I need help... have a 2012 donfang mc-d250rtc. My headlights will not function. The running light is on but when i start the bike the headlights do not switch on. the only way I have lights is if i switch on the highbeams... then only the left side comes on...."

He PMed me but maybe someone that has had this problem knows the answer?

Sounds like the low beam is not working.

I'd check the bulb first.
