You didn't say what your purpose is for the light...........but for fishing green is best, for looks it's up to you. I think I saw a video a little while back about the ebay drain plug lights being very weak.......... how many lumens are the ones you are looking at?
If you are handy you can make your own for far less money that is a lot brighter.......... but don't think it will ever work as well a expensive one.
