Installation what simple and straightforward. The most intense part is surely the cleaning and preparation of the plastic splash guard. I haven’t had a chance to ride yet, as it’s still too cold here in the North East. Preliminary testing of the product shows that all functions are indeed working. It’s hard to tell how bright these are, as installation and testing was done in a well lit garage. I only gave 4 stars because they are held on only by adhesive, and the fact the splash shield they stick to is slightly textured, not smooth and slick. I’m simply not sure how well the adhesive will hold up out in the elements, so I didn’t go all-out in my rating. I would rather have seen a plastic with screw lugs that share the same three holes as the splash shield, which would eliminate any worries about the adhesive failing. I’m definitely looking forward to riding with these though! Thank you, Harvey, for fabulous service and speedy shipping!!
