From the specifications IIRC not enough run time for continuous daytime use on a tour. The 400R with multiple large battery packs would be needed IMO if you want continuous daytime taillight operation on high.
Personally I am not sure a taillight, even a bright one, adds that much to daytime visibility in sunny conditions.
