These days, there are several cases that people bump into others and get hurt because we do a lot of outdoor workout even at night time. So lighting can be a communicative way to inform other people their positions for the safety in the dark. For that reason, we made a kind of cup holder with lighting to use on the water bottle before the actual accident happen.
