So I am working on my Gears of War armor/costume for San Diego Comic-Con. I wanted to add some accent LED's to my helmet and my armor. Now I know how to wire up LED's and all of that. (thanks to some help from great people from here). But to be honest I don't feel like messing with them again LoL. Now the other day at Walmart I came across these.

Now the kind I posted here are not the exact ones I saw at the store. I was just using this as an example. The ones I saw can be shortened. Now a couple of things. These are made to be hooked up to a 12V system. These do have a try me button so you can see how they light up. My question is this. Do you think its possible to switch out the try me button with a latching switch, throw in a 9V battery and use it like that?
