The D1 is a super compact but powerful backup light. It is made from aircraft grade alloy and features a twist to on and double O-Ring seal.
The best part is it uses a single AA alkaline battery, meaning it will be ready after months of sitting in your tub, unlike lithium rechargeable lights that dissipate charge in storage.
