I LIKE TRAFFIC LIGHTS AND HAVE FOR A WHILEEEEEEE! I like many things with lighting and noises and stuff and traffic lights & streetlights are an everyday accourance for meh! This is a recreation of the T-Con/Kentron Era Incandescent as the soon moved over from being made by Kentron to being made by Econlite but I think that not much changed designwise. This is the twelve inch version, still with my CFL because I didn't go to www.lamptech.co.uk to see some incandescent luminaire designs which is the site where I get all my bulb designs. This pack utilizes a new Visor, The Durasig/Alusig front door, an average 3 stack vertical fixture & a doghouse fixture.
