Lights are used to make bike visible to others during daytime rides on the road and bike trails. The 1000 front light is operated in pulse mode (setting 4). Battery life has been good for a 70 mile ride so far. I normally charge overnight. Others have commented that the pulse modes of both lights make the bike highly visible. Have not tried the 1000 light for night riding. The charge port cover attachments could be more robust for regular use.
