What is your goal? It makes a huge difference between diode's and lamps, and what you actually want to do.

Then as Carl mentions a LED bar graph display where the LEDs react to for example an audio signal volume or frequency. You really need to better express what you want. A circuit like this one will give one of the example images I posted. A Google of "LED CHASER CIRCUIT" will bring up many variations.
