Thanks in advanced

Acer, we have no idea whatsoever what you are trying to accomplish. Since you decided not to reveal anything about where you are located or what your interests or background is, we have no idea how to help you.
If you are in the United States or Canada, I might suggest that you go to a Radio Shack store and buy their basic Forrest Mims' notebook on opto-electronic components and applications (they are cheap, but not very available anymore) and suggest that you study a little, then ask a question we can understand.
Wherever you are, you can access some LED spec sheets and app. notes on the web and see how LEDs are applied.
If you are asking about how to solder, google "soldering," and you will get almost 2 million items, the first few of which are excellent tutorials on soldering procedures and techniques.
Put yourself in the position of someone who does not already know what you are trying to do and imagine how we can decipher anything from your illustration of a rectangle with a bunch of circles and ovals in it. This has nothing to do with your stated low level of understanding of electronics, which we are all interested in helping you with. It has to do with basic communications.
Don't be discouraged by our bafflement. Just try to explain yourself.

eblc1388 said:Million dollar questions:
1. how many leds?
2. same or different colors, what color?
3. battery drive (+12V or not) or from AC power adaptor?
Without answer to these no more suggestion is possible.

Something like this one. I took it out of a dead artificial candle. its a flashing LED in an red plastic case...
