If anyone is interested in using these, please let me know. Red: 4 Black: 4 These are not made by amateurs. They are made by someone who works on car electrical systems, so you can use them with confidence. For passenger cars, they can be used for audio, ETC, LED lighting, and other customizations. For trucks, they can be used for adding side markers, sign lights, and other customizations. Compatible with both 12V and 24V. Thank you. If a buyer has a request, I can make it.
