I got these two lights from my friend, but hes not doing the best job explaining what is what. I have a single purple light, and also a two-in-one light that has a bright light on one end and a purple-y light similar to the first on the other, when I hit the switch, both lights come on. Will someone please tell me the use for each of these lights and when I should use which light? Pics enclosed below.
