After a few close encounters with cars driving my longboard to work at night, I decided to make myself more visible. I used 3M tape to attach my head and tail light and had no vision issues, these things are BRIGHT! Combine this with a standard size AAA battery (not included but easier to find than a watch battery) and I couldn't be happier. The battery compartment does not have a watertight seal, but can easily be taped shut and made watertight. I beat them to death too and they are holding up great.
