I think faulty light switch.
Low beams
Pull back on the turn signal lever to change from high beams to low beams If the turn signal lever is pushed forward the high beams stay on and if the turn signal lever is pulled back all the way that is the " flash to pass " feature
the low beams should turn on when the motorcycle is turned on
dont
sounds like you have a short in the low and hgh beam switch take it to auto electrician
Sounds like it needs a headlight switch.
Often it can actually be a faulty turn signal!! As silly as this sounds it is quite common. First thing to do is clean the contacts on the turn signal, if you still get high beams and no low beams you probably need to replace the turn signal switch.
The switch assembly is probably worn out and malfunctioning.
Turn Signals, Low Beams, High Beams and Flashers
Your low beams are burnt out. that happens alot
Bad dimmer switch.
