Separate 24 volt circuits to LED Headlights

[Hunter450]

Let me preface this by saying that I apply the KISS approach whenever possible. I have a need to add only headlights to my cart and do not plan to add any future accessories. I have struggled with the DC-DC reducer vs the separate 12 volt battery option and really didn't like either of those for just headlights.... remember, keep it simple.

I have found LED pod lights that operate between 9-50 VDC.

My questions are:

1.) Would there be any issues wiring the lights individually with 24 volts by dividing the pack voltage (6-8V) equally through a DPST switch? Basically batteries 1-3 would power one light and batteries 4-6 would power the other light. This would be a balanced draw on the pack operating through a single switch.
2.) Can I wire the (-) ground wire on the light back to any negative post on the half pack that is supplying the 24 volt power?
