Plug it into the cigarette lighter socket via the controller. Plug electrical lamps, etc., into the cigarette lighter socket. Lights can be turned on by switching the controller's mode. You can enjoy flashing lights that react to audio via the sound sensor. The flashing interval can also be adjusted with the lever. Regarding electrical lamps, such as LED lights and LED strips, I think you can enjoy various ways of using them if you come up with ideas and connect them to the cigarette lighter socket. Operation has been confirmed. I bought this a long time ago, but I haven't used it much. It has been stored at home. I would be happy if someone could use it. I will ship it in simple packaging.
