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 a certified automotive electrician, 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 side marker lights, sign lights, and other customizations. Compatible with both 12V and 24V. Thank you. If a buyer has a request, I can make it. There is plenty of stock, so the price will vary depending on the quantity. I am also selling other items, so thank you.
