Best thing would be to buy a voltage convertor. Something like this:
DC to DC converter, robust, heavy Duty industrial, marine and military quality voltage converters 12V to 24V DC/DC converters (fully regulated) from 120 Watts with common negative ground.

I don`t have experience with a dual battery system but looking at a few diagrams I don`t think that would work since the batteries are wired in parallel and isolated.
There are only two ways:
a second alternator running 24v (2 batteries in series)
Or,
an isolator/topcharger converting 12 volt to 24v to charge a second bank of batteries, again, in series.
I ran this setup to for OBA-- an Oasis HP 1000 that was putting out about 16 CFM at 100 psi. It was just way too fast even for my air-hungry rig (Active air suspension, air lockers, CTIS, etc. all eating up gobs of air)
I pulled the topcharger off after only a few minutes after realizing that it was way, way overkill and just run my compressor off of 12v with the same battery bank now wired in parallel.
It is nice to have a compressor that can do both, but 24v is just too much speed.
So, now I have a mil-spec, ridiculous bombproof quality topcharger that I paid $1000 for sitting in my basement.
So, it is for sale but it is a small, very small, microscopic market for this stuff. Make an offer or come up with an interesting trade.

It can be done. It would take a lot of isolators and is just begging for big trouble. ECUs dont like 24v. An up-convertor is the best way to do it, if your set on using 24v lights.

Many LEDS can run from 6v-24v
I'd try pushing one with 12v and see if it reacts, and may even be something internal that can be removed that may allow it to run on 12....
send me two and I'll let you know..:thumb3:

That's because LEDs don't have resistance to limit their current, and use resistors, which obviously changes based on the voltage you intend to feed them. Twice the current, twice the light output. Until their package can't dissipate the heat or you exceed the package's voltage limit, of course.
Incandescent bulbs have resistance of their own. meaning they themselves are current-limiting, and thus have a narrow voltage range.
