Can LED lights be used on a timer?

LEDs do not work on all timers. This is also the case with many energy saving bulbs. The timer lets enough voltage thru to partially light the LEDs and energy saving bulbs. LEDs will light fully when the timer is "on", but will continue to light dimly when the timer says "off". Energy saving bulbs will have a dim flicker when "off" thru a timer. I have not found a timer yet that solves this problem. If anyone knows of a solution I'd love to be able to use energy efficient lights with the convenience of a timer.
