    do you want to rotate a single led, or have multiple leds in a circle, where only one led is on, and progressively the next one is turned on? If so, how many leds?

    Look in google for an LED Chaser Circuit. They use an oscillator clocking a CD4017 IC that drives 10 LEDs.

    I have three red ones, an orange, a yellow, a blue and a green LED Chaser.
    They run for months on two or four AA alkaline battery cells and are very bright.
    Instead of an LED always turned on, the LEDs blink for a moment then after chasing around a few times there is a pause. Then the average battery current is very low.
    The LEDs are in a circle mounted on a CD.

    At night the blue and green ones light up car reflective licence plates pretty far away.
