Designed solely for installing Silver Bullets or Mini Bullets on Metric Cruiser fender struts. Specialised hollow mounting studs are 3/8”-16 on one end to thread into the light body & M8-1.25 on the other end to install in place of a fender strut mounting bolt on most Metric Cruisers. Select any of the Silver Bullets with 3/8”-16 hollow mounting bolts or any L.E.D. Mini Bullets. M8-1.25 is very common on Honda, Kawasaki, Suzuki, & Yamaha fender struts but confirm suitability before ordering.
