I installed spiral fluorescent light bulbs and a motion activated light switch for my kitchen light and noticed that it flickered when it was inactivated. From what I understand, the motion switch doesn't stop the current completely; it uses a small amount to run the motion sensor. That small amunt of current will build up in the flourescent bulb and discharge causing it to flicker. Fortunately, the light fixture I had held two bulbs and I simply replaced one of the two spiral fluoresent bulbs with a regular incandescent bulb and the flickering stopped. Based on that,I assume some current is still getting to yourlight bulb which is causing it to flicker.
