Come on guys, this guy is all of us on a budget, but actually USING his lights for something worthwhile.
He has multi level incandescent lighting, the best of the best for color rendition under all outside circumstances, and on top of that, during the day he has BRIGHT side markers!
I wasn't kidding above when I said that if he gets hit the driver has NO excuse!
That said, that isn't a beater bike. Look closely at the paint, handlebar end mirrors, gel seat, wheel reflectors that are in good shape, etc.
That's somebodies cruiser bike that has some whimsy and a need for cheap light sources for riding. If I had to guess, it's an East Coast, Nantucket/Chesapeake Bay/Martha's Vineyard kind of bike. OR alternatively, a Washington State beach/island bike, or possibly the Oregon coast or Santa Cruz, CA area. All those areas seem to attract the whimsical people with a practical side who would see no contradiction in using battery powered lights on a bicycle.
Besides that, maybe all those are rechargeables!!
