This is a 3LED slim cycle light from Smile Kids Asahi Denki Kasei. It's designed to be mounted on the handlebars. It uses three AAA alkaline batteries and features high-intensity LEDs. The continuous lighting time is 24 hours, and the continuous flashing time is 48 hours. It's water-resistant, so it can be used on rainy days. The light can also be removed and used separately. How about using it as a spare light for your bicycle? Shipping is planned via the anonymous Mercari shipping service. Thank you.
