Reply to "Reducing brightness of a billboard display"

OK, LEDs. A single 1k will definitely drop the brightness and like you say you'll get more dimming with two. No harm in doing so. I'm guessing that 1k may actually be too large in which case take two 1k and tie them in parallel (side-by-side, rather than end-to-end) to effectively make a 500 ohm (=1k /2) resistor. And if that is still too dim, put 3 of the 1k side-by-side in parallel to make a 333 ohm (=1k /3) resistor.
