How do I hook up a 1.5v solar outdoor diode light without the solar panel to a 12v battery bank in a motorhome?

I have a cheap four color diode from a rechargeable solar outdoor light that I want to install inside my motorhome and run it off my 12v battery bank but I need to know how to reduce the power so that it will not burn out the diode.
It works fine without the solar cell except that it wears out the 1.5 AA batteries that it uses.
I am sure that it would take forever to run down the six 6v golf cart batteries that I use for power in my RV, especially since they get recharged every time I run the RV.
Any answers out there?
How do I do that?

Solar powering an Radio Contoled car for recharge power only?

So I have a couple solar cells off some outdoor yard lights that I replaced with new up to date lights so these were for parts. I know solar panels produce power during light but during no light conditions have the ability to suck power back out of the battery being charged, so a diode must be used…..? What would someone recommend as a high efficiency diode to be used(i think germanium??) or rating or part number. Then do I have this right, my 2 solar panels(2inch X 2inch) can go either in parallel or series as this is only charging and not a direct supply source, will one be better config. than the other? (Parallel or series??). I should be able to solder on the PC board where the NiCad batt wires go…..I’m thinking this is ok because the PC board has a On Off switch and will only allow solar power to flow into battery only, no other components thus having WHILE POWER SWITCH IS IN OFF POSITION AND SUNNY should charge batter.?? Do I have this right or am I missing components. Positve solar wire to positive batt wire negative to negative,
