Thank you for viewing. Miright is often used for night fishing with Yaen, isn't it? It's attached to the reel to indicate a bite, or attached to the Yaen to show its location, or attached to the rod tip. It's brighter than chemical light sticks and has significantly lower running costs than Miright. Please select a color and contact me. This is just the LED light itself. Please be aware that the holders in the photos are not included. Additional lights are 150 yen each. CR311 batteries are used. One battery for testing is included. Additional batteries are 100 yen each. Please comment first. I will create a dedicated listing for you.
