How do you attach your chest lights to your armor/ vest?

I just got shackman's great chest lights and now need to know how to attach them to my armor. I don't want it to be permant as I plan on upgrading my armor in the not so distant future. Any idea/pics would be great.

It sounds kinda shoddy, but I simply duct taped my shackman lights to the back of the armour plate, and then cut a hole in my vest so the amrour would sit flush against it. I've had it taped for over a year, and with all the trying it on & taking it off, it has never moved a Millimeter. Theres probably a better way of doing it, but duct tape really has worked good for me Something to try if you can't come up with other options

Yeah, I'm also using duct tape. Can't really think of any other way to do it.

Hot Glue Gun Baby! I just lightly glued the edges and it works great.

i used hot glue , but first i put a piece of limo tint over the holes with super glue , just to give it a darker look so you cant see the lights when they are off .i'll put up a pic tomorrow of my power supply box for the shackman lights .
