My SO has several of these, which he uses on his cargo bike. They look really striking. He says the "amber" one isn't very good, but I'm not sure if that's yellow or orange on that page. The other colors are all nice and bright. He uses rechargeable batteries in them.


(He's always wanted a stoke monkey, but finances haven't allowed. So, I bought him a stuffed monkey (which is actually a gorilla, but whatever) and zip-tied it to the bike under the seat in front of the cargo extender thingy. He's taken the blue one of these and highlights the monkey. He get's "Hey, look, he's got a monkey" yelled at him all the time when he rides at night or dusk.)
