If you're talking about adding LEDs to the fan blades -- I don't think you're going to be able to retrofit that easily, and if you could I think you'd ruin the fan as a fan.

The canonical way to set up the parts you have there would be to use the switch to control the hot side of the AC line (preferably, although I'm not sure you have a polarized plug there), connect from there to one side of both the 110V status light and the 110V fan, then connect the other side of both the fan and light to AC neutral. Switch on, both light and fan are powered; switch off, neither is.

Note: I'm assuming the status light is a NE2 neon lamp or other 110V light. If it was intended to take a lower voltage, you need to supply that voltage via either a dropping resistor or a suitable power supply.

(BTW, if the preceding two paragraphs weren't immediately obvious to you, I strongly suggest that you work with someone, or get someone to check your work before you plug this in.)

i got it as is and have been trying to think of what to do with it. I know the dangers of 120V, but i will proably change the plug to a polariced on for saftey so i dont shcok and/or kill me or someone

Polarized plug is a good precaution to ensure you know which connection is hot and which is neutral. (The switch, of course, should control the hot side.)

BUT THE RIGHT ANSWER is to assume that it's all electrically live unless it's unplugged. Especially since sometimes outlets get wired backward, in which case the polarized plug would be doing the _wrong_ thing.

120VAC (or 240V in Europe or for some US equipment) is inherently Not Safe. It can be handled safely, but it's up to you to know what you're doing. If you have to ask, PLEASE get someone else to check your work.

it emits a orange light when is on, i dropped it and some wire broke off so thats why i can power it safely anymore. I dont mind putting a lighted switch

Orange light probably is a neon glow bulb.

+1 to the last bit.

Those are uninsulated terminals.  If you have those flapping around naked in your computer case, the least damage they can do is to kill your computer. 
If you're unlucky, they can kill you.

not going in a computer case, the thing about the 12v power thing is for powering seprate leds

i mean as a 2nd switch with leds to act as a light but not on the fan

If you like soldering, it would make a mighty fine fume extractor/blower-awayer
Studying the effects of air pressure
Chase people around with it and watch them scream in terror
Computer case mod (would take quite a bit of effort tho)
trying to remove the motor for a project
etc... im out of ideas for now :)

lol oops i took your title a bit too literally and didnt read all the way thru your post (silly me *slaps head*)

hmm... best bet on leds is with coin cell batteries superglued (or duct taped) to the fan blades maybe, would set the fan off balance and have it vibrate unless the weight is equally distributed
