I just installed my light strip this week. I had ordered on ebay and they came from China, first mistake. I have an RF controller. The red power light comes on and the green signal light blinks green when I turn on via a 12v switch I installed. The lights lit up green. I had to put a battery in the hand held transmitter and whoa en behold, nothing happened. Could not change colors or turn on or off. The transmitter and controller must be matched and apparently either one or the other has a problem or not matched. I ordered a new controller and transmitter from an outfit in ST Louis. Should get here tomorrow and then I can test.
