580898 Proton module LED 3-1 turn signal combo ECE appr.

The MCS Proton module is a highly compact 3-in-1 LED lighting solution that combines taillight, brake light, and turn signal functions into a single miniature unit. Featuring red LEDs for rear lighting and amber LEDs for signaling, this module is housed in a metal body with a tinted lens and measures only 11mm in diameter. It is designed for custom integration, such as laminating into bodywork or mounting via its M3 threaded stud. ECE approved for rear use and sold as a pair, this module (OEM 580898) is perfect for minimalist Harley-Davidson builds where discreet yet powerful lighting is required.
