I'm curious -- since this is a standard vehicle tail light, approved by the U.S. Department of Transportation, why is it too bright for night use? Is it not normally bright for day and night use? Or is it too bright for a cyclist in line right behind you?

Daytime 400R tail light is advertised only for daytime use, claiming 240 lumens (or 400+, depending on where you look on their site). (But since they have a steady mode at 10% power, it seems like that mode would be appropriate at night, too.)
