Free Exit Sign Lighting

I have a stack of Vanex Exit Sign Lights. I am not sure if they are NYC approved and if NYC even approves exit signs. what these are is Vandal Resistant Exit Signs. they are shielded inside a poly carbonate shell such as Plexiglas. I suspect there is battery back up. i have a bunch of them – at least 15 here in NYC and more stored on LI. Free to all including contractors. Do not call me. Visit my website and send me an email. Pick up in Middle Village Queens. Steve http://brownstoner.staging.wpengine.com/thetinkerswagon
