Headlights on m5030dt not working properly

[GEARHEAD34]

The headlights on my m5030dt are not working properly, or at least i don't think they do!
Only one headlight will work at a time, not both left and right at the same time.
Has anyone else had this problem?

Is it the same on high beam and low beam; maybe one of the filaments burned out, just a WAG...

Check the ground wires.

Yes, it is the same on high and low beam.

Both headlights will not come on at the same time.
One light at a time. Installed a new switch last week.
Nothing changed...

Then I have officially exhausted my knowledge base as to electrical components. My son and I installed (OK he did it and I watched) a new dash module on my Rhino and didn't get one of the wires seated quite right...now I am out of even guesses.

Could the high and low beam wires be reversed on one side? I am assuming that you are getting one or the other to come on by using the dimmer switch.

Thank you to Beemer 530 and the other suggestions.
I did have the wires reversed . Duh !!!
