    The light project "PRICELE$$"! I live central in the city of Stockton CA. My city is ticketly ""very"" serious about lights on bikes after dark. I have given more flashlights to my group of bicycling associates than I ever owned. lol
    This definitely has a trade/street value for parts & accessories.
