I don't mean to contradict Roger, but LEDs are current opperated deviced.
So a current liniting resistor in serise will reduce the light output.
But the reostat used for a light bulb won't work.
Resistance would likely be way too low.

Can you point me to an appropriate reostat?


More like a variable resistor.

Reostats are usually wire wound for higher current - like a light bulb.

LEDs, at least the one's I'd use for this kind of thing, barely pull
10mA/diode. A single bright white LED running at 12 volts - golly,
I'd start about 200 ohms fixed resistor and see how bright the light is
at 50 feet.
