This can be due to a fault with the switch that switches from low to high beam as I have seen fail before in the past needing replaced.I have also seen issues with a low beam control relay as well.If you have a multi meter or test light to test electrical with I can try and walk you through some testing to see if we can pinpoint the fault just let me know.If you do not then the low beam circuit needs tested to see if this is a relay or control unit/ecu fault or the light dimmer switch itself.
