Bought these for the kids bikes & they love them.
Works with 1 AA battery & very easy to install.
Not only do they look good but they’ve added another safety element to their bikes as they’re definitely seen!!
I purchased quite a few & have also used these in their rooms around shelves.
I’m sure there’s many more things they could be utilised with.
Great price & a brilliant way to keep the kids safe out on their bikes.
