rgb lit rgb splitter has an internal rgb diode installed and the case is frosted clear acrylic,  it will have the same color as the strip installed so it will be sync with any strip you hook up to it, this is just the splitter and no controller is included so you will need to have an rgb input via a controller or use an extension cable from any 4 pin rgb header to feed this splitter and hook everything up to it.
 
I have had customers who get several RGB items and without having a separate controller for all of them I started making these splitters so that you could use 1 inline controller supplied with all my RGB items and now control up to 3 items from the same controller and this allows for only one connection to your PSU and all your RGB covers will be synced together.
