Even more safety on the way to school: Drizzle, fog, snowfall, and twilight? Visibility is especially important during the darker seasons. The darkness and poor visibility can cause other road users to notice your child late, which is why it makes sense to equip or retrofit the coocazoo school backpack with an LED safety clip light. The coocazoo LED safety clip light can be easily attached with a clip. You can easily adjust the light with a push button. You decide whether to have a constant light or whether the light clip blinks quickly or slowly. The battery is replaceable at any time, and the delivery includes 2 CR2032 button cells.
