If anyone is interested in using these, please let me know. Red: 5 Black: 5 These are not made by amateurs. They are made by a certified automotive electrical technician, so you can use them with confidence. They can be used in passenger cars for audio, ETC, LED decorations, etc. In trucks, they can be used for side marker expansion, sign lights, decorations, etc. Compatible with both 12V and 24V. Thank you. There is plenty of stock, and the price will change depending on the number of pieces. For example, 20 pieces would be 2000 (currency not specified). I am also selling other items, so please take a look.
