damn bright? What's mean? Anyway~ I guess your question is about the LED light. It is called "Line Watching LED Light" in Korea. You can get the information in below URL. smartstore.naver.com/fishingdog/products/4046957606?NaPm=ct%3Dkhvc22h4%7Cci%3D72fb47a357fe379aaa0fc922f9674f4ef6118a7a%7Ctr%3Dsls%7Csn%3D820692%7Chk%3D6827b2287754e654312fabe3d03f0525053c1fc7
