I don't agree. There's a guy who regularly rides a route similar to mine who has a bright jersey and a puny taillight. Every time I see the guy I'm struck by how far away I can see his jersey, but that I can't see his light unless he's just in front of me. In bright sunlight, it takes a bright light to be seen.
