<CENTER><H2><B>Simple Bicycle Rear Light Carrier Rack Adapter<BR>For 50->80mm and 80->50mm Conversions</B></H2></CENTER> There are two main standards of bicycle rear carrier rack rear light mounting points using either 50mm and 80mm bolt distance. Some carrier racks have holes for both standards, but some have only either, usually older or city bikes may have 80mm holes and most of the newer, modern bikes racks may have only 50mm holes. You may have bought a rear light that that doesn't fit the holes of your bike's carrier rack so here's an adapter for either way conversion. Note that the structure of your carrier rack may affect the suitability of the adapters for use, this is just a simple solution that hopefully will work in most cases at least. To assemble you need two M5x16mm hexagonal screws for the adaptation holes. Hope you figure out the use yourself, its pretty straight forward after all.
