They are designed for 12v ( for cars etc ). Basically led at one end with
2 wires ( red & black ) coming off it.
Touch the red ( + ) to the + on the battery, black ( - ) to the - on the battery and you get a nice little purple glow
I'm guessing that it's just a case of attatching them to existing wiring ( maybe unused wires meant for indicators ? ), put a switch inline, and off you go, but best to be sure

I did also find strobes, headlight flashers, amps, monitor and a whole selection of under car led strips, but i think that might be going a little bit too far
