Somewhat still in the submittal process but we have pole lights that are run on a normal lighting circuit and have an obstruction light that mounts to the top of the pole that is being fed from an emergency circuit.
I’m pretty sure it’s against code to run both normal and emergency circuits in the same raceway that is the pole. Is there any way around this, ie if we were to run a certain type of cable inside the pole would it still apply?

410.30(B) poles shall be permitted as a raceway so I would say the OP question would pertain to 700.10(B) as in example we don’t permit CCTV cables in the light pole with the lighting conductors 820.133
 
Are the underground conduits already installed, and if yes, how many individual conduits feed the light?

I believe but don't have my code book in front of me, that the issue addressed in the above statement around the 700.10(B) is because these wire types have different insulation properties, CCTV cables are not rated to 600V as normal circuit wire would be. Key words above in quoted 410.30(B) I think are "shall be permitted" not "must be used".
So the OP? can be answered by using flex conduit for the emergency circuit as that would then put the E circuit in it's own raceway.
Also look at and confirm the listing as "emergency circuit" the definition is very specific as to what is an "emergency circuit", we sometimes will use the term in error ie: home owner wants an "emergency generator" for if the power goes off, he has medical equipment that he wants to keep operating, but all he needs is a standby generator. If he had an "emergency generator" that would put in all sorts of additional regulations that he never needed or intended.

I was going to say the same thing. These are aircraft obstruction lights, does that make them emergency lights? Just because some engineer thinks they should be powered from an "emergency circuit" doesn't make it so.

They are not. In fact, they're largely spurious unless they are on an obstruction of 200' above ground level or you are very close to an airport.
