Sounds like no extra circuitry in your flashlight, but that makes sense since the voltage will remain in a defined range.  Charge cycles on a lead-acid battery can send voltages over 15 volts so it makes sense to limit that, or the voltage can go down to 11 volts so it makes sense to boost that to maintain the light output.

Each light has its own switch so each one would need a pot in the correct ohm range.

I know the ones in my flashlights don't put out the same lumens until the batteries die; they get dimmer as the batteries get older.  I'd be happy to swap out my LED's for that kind if I knew where to install the master potentiometer.

Depending on how the LEDs are driven, you might be able to use a simple potentiometer to dim them (somewhat), or you may not be able to dim them at all (unless you replace them, or modify them). Some LED packages have boost/trim electronics on them which will prevent them from being dimmed.

They should be bright, but why is it better that bright be the only option?  I personally like long talks over drinks in comfortable light.
Is there no place where a master dimmer could be installed?

If you don't mind killing the warranty on your factory LED lights and doing your own wiring/caulking, there are quite a few camper dome 12v LED with built in dimmers on Amazon.

You can replace them with "warm white" LED bulbs.....I believe from Amazon.

I like the bright lights in my 179 also. I guess it must be my old eyes that need the bright light!!

BTW, my understanding is that not all led light bulbs can be dimmed.

I'm sure that I'm in the minority here,  but I love the lights in our 179.  Yes, they are bright, thankfully.
