The tradition to use reflective ornaments goes back to 1940’s when they first appeard in HD accessory catalogs. The Red Fox dots feature real glass lenses and are authentic reproductions of period parts. With their 4-tab rim they can be easily applied on saddlebags, leather or jeans jackets, etc. Installation on hard surfaces like fiberglass bags or taillight lenses requires drilling of a 15/16” (= 24 mm) hole.
