I want to know what ic chip or microcontroller is in the inova micro light? i would like to make something like it.?

it has three modes that you are able to press down on the button the first mode when you press the button once you have solid line of light when you move it quick then when you press it two times the light is sort of dimmed where you see a dotted line when you move it quick and the last one is continuous flashes

They're using a microcontroller to flicker the led to create various intensities of light (thats how the brightness works)...

Making your own is as simple as learning microcontrollers, circuit design, and programming one to do as you wish.

If you want a hardware only 'passive' solution, use lemonie's suggestion -- the 555 timer can create that pulse-width-modulation brightness control simpler, but without the buton-press-mode-changs.

Lastly, you can buy that circuit for a few dollars -- they are tiny, designed to fit in flashlights. Various diy flashlight websites sell them. I know dealextreme has them.

yea i did the 555 timer one i was like cool, but i want to control the mode of the light so it could be varied with a push of a button and the little smd microcontroller on the inovas pcb board has 6 pins and i was like wondering what microcontroller is it so i could buy it and it also runs out of a surface mount capacitor and a surface mount resistor and well with the 555 timer you have to like put about 3 resistors and capacitor to make it flash and i was like how do you set it up with just about 3 components that are the button switch, capacitor and resistor
Okay;

1. Use punctuation. (properly). You just wrote one long sentence, and I have no idea what you want to do.

2. That is all.

Sorry i hope this is more understandable.

I did the 555 timer already, but i want to control the mode of the light so it could be varied with a push of a button.
The Surface Mount Microcontroller on the Inovas PCB board has 6 pins and i was like wondering what microcontroller is it, so i could buy it. It runs out of a surface mount capacitor and a surface mount resistor, however, with the 555 timer you have to connect about 3 resistors and a capacitor to make it flash continuously. I was wondering how do you set it up with just about 3 components that are just the button switch, capacitor and resistor just like you would see on the Inovas Pcb Board.
I took a picture. The quality sucks though but you could barely figure out what is what. By the way i saw closely on the microcontroller and it says 11PE im not sure if that helps but i hope it does to tell what type is it.

Okay, so the 555 timer is a logic chip. It simply oscillates based on the resistors and capacitors you hook up in an endless loop.

The chip in the light is a programmable microcontroller. I don't know which one and searching hasn't told me anything. Basically, it runs a full computer program, and changes how the light flashes when the button is pressed. Search microcontroller here on instructables to learn more. There are lots of projects.

For flashing things (these are flashing or not-flashing) look at 555 circuits perhaps:
