Have you tried using a potentiometer? You may be able to lower the voltage going to the LEDs and cause them to dim. It depends on how the LEDs are configured inside the rope, though.

you'd need a pwm signal.

to blink the lights fast enough that they look dimmer

i agree with boyswidtoys, leds don't take to dimming very well, they need to flash rather fast at 3/4 potential to make them look dim, sux i know but its one of few downsides to leds

modest yet effective... ECLIPSE 12", Venom 8"x2, Focal 5 1/2" comp.,Response amps x2 (580WRMS total @ 4Ohms), Pioneer TFT + DVD, good for 148.7dB
