It's a pretty cool cosmetic thing you can put on your blaster. I decided to put the 2 I bought on my nemisis hopper, and looks pretty cool. If you put enough power through it, you could probably stuff like 5-6 of these in a blaster with a thin she'll, cause the lights are strong enough to kinda go through plastic. My only complaint is that the tape that's mean to hold the lights to what ever you put them on isn't sticky enough, so I used super glue.
