Since you can't be too safe, here's an alternative to the daytime
strobe: Sonic protection!  They'll hear you coming!

Apparently the photo is just a prototype, since the actual unit "draws
power from a rechargeable internal battery, or your hub generator."
I'm a generator fan, of course, but I'm not sure I'd like the one used
in the photo.

a sonic headnet receiver for fire fighters was in Google News...thought of hearing background noide for boat trailers vs tri ax et al each distincive. After road miles on the quiet outback one can differentiate drunks from non drunks, Expolorers from Surburbans, the S'ers getting lower grades.

I have a position at closing at the gate where more and more hybrids noiselessly move out. Owners are prob oblivious types...Cafe Eco.

I rec the hybrids get the sounds of a starving pig.
