I bought these for our church golf cart for the volunteer safety team. You don't need anything expensive or fancy, use what works as described. I got these, connected to the power supply and they lit up, the colors are sold, they are bright, but when you press the buttons on the remote nothing happens, the indicators do not change mode. The remote light comes on to let you know the batteries in the remote are good, but it just doesn't change lighting modes, no strobe effects.
