Just 2 days ago I saw a roadie go over a bump on the local MUP & his tail light fell off & broke. Modern lights are bright & light but they really cheap out on the brackets, would be nice if lights used a standard mounting design so that various brackets would work. I had to rig up an ugly plastic bracket for a Tubus rack since the Serfas tail light didn't have the standard German bolt hole spacing. OTOH, I don't understand why B&M & other German companies don't make flashing tail lights for the export market. Maybe use a nice German rack-mounted tail light & use a helmet-mounted flashing tail-light?
